Form

High performance Form component with data scope management. Including data collection, verification, and styles.

When to use

When you need to create an instance or collect information.
When you need to validate fields in certain rules.

Examples

Basic Form data control. Includes layout, initial values, validation and submit.

TypeScript
JavaScript
import React from 'react';
import { Button, Checkbox, Form, Input } from 'antd';

const onFinish = (values: any) => {
  console.log('Success:', values);
};

const onFinishFailed = (errorInfo: any) => {
  console.log('Failed:', errorInfo);
};

const App: React.FC = () => (
  <Form
    name="basic"
    labelCol={{ span: 8 }}
    wrapperCol={{ span: 16 }}
    style={{ maxWidth: 600 }}
    initialValues={{ remember: true }}
    onFinish={onFinish}
    onFinishFailed={onFinishFailed}
    autoComplete="off"
  >
    <Form.Item
      label="Username"
      name="username"
      rules={[{ required: true, message: 'Please input your username!' }]}
    >
      <Input />
    </Form.Item>

    <Form.Item
      label="Password"
      name="password"
      rules={[{ required: true, message: 'Please input your password!' }]}
    >
      <Input.Password />
    </Form.Item>

    <Form.Item name="remember" valuePropName="checked" wrapperCol={{ offset: 8, span: 16 }}>
      <Checkbox>Remember me</Checkbox>
    </Form.Item>

    <Form.Item wrapperCol={{ offset: 8, span: 16 }}>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

Form methods

Call form method with Form.useForm.

Note that useForm is a React Hooks that only works in functional component.

TypeScript
JavaScript
import { Button, Form, Input, Select } from 'antd';
import React from 'react';

const { Option } = Select;

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

const tailLayout = {
  wrapperCol: { offset: 8, span: 16 },
};

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onGenderChange = (value: string) => {
    switch (value) {
      case 'male':
        form.setFieldsValue({ note: 'Hi, man!' });
        break;
      case 'female':
        form.setFieldsValue({ note: 'Hi, lady!' });
        break;
      case 'other':
        form.setFieldsValue({ note: 'Hi there!' });
        break;
      default:
    }
  };

  const onFinish = (values: any) => {
    console.log(values);
  };

  const onReset = () => {
    form.resetFields();
  };

  const onFill = () => {
    form.setFieldsValue({ note: 'Hello world!', gender: 'male' });
  };

  return (
    <Form
      {...layout}
      form={form}
      name="control-hooks"
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
    >
      <Form.Item name="note" label="Note" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item name="gender" label="Gender" rules={[{ required: true }]}>
        <Select
          placeholder="Select a option and change input text above"
          onChange={onGenderChange}
          allowClear
        >
          <Option value="male">male</Option>
          <Option value="female">female</Option>
          <Option value="other">other</Option>
        </Select>
      </Form.Item>
      <Form.Item
        noStyle
        shouldUpdate={(prevValues, currentValues) => prevValues.gender !== currentValues.gender}
      >
        {({ getFieldValue }) =>
          getFieldValue('gender') === 'other' ? (
            <Form.Item name="customizeGender" label="Customize Gender" rules={[{ required: true }]}>
              <Input />
            </Form.Item>
          ) : null
        }
      </Form.Item>
      <Form.Item {...tailLayout}>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
        <Button htmlType="button" onClick={onReset}>
          Reset
        </Button>
        <Button type="link" htmlType="button" onClick={onFill}>
          Fill form
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;
#components-form-demo-control-hooks .ant-btn {
  margin-right: 8px;
}

Form methods (Class component)

We recommend use Form.useForm to create data control. If you are using class component, you can get it by ref.

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, Select } from 'antd';
import type { FormInstance } from 'antd/es/form';

const { Option } = Select;

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

const tailLayout = {
  wrapperCol: { offset: 8, span: 16 },
};

const App: React.FC = () => {
  const formRef = React.useRef<FormInstance>(null);

  const onGenderChange = (value: string) => {
    switch (value) {
      case 'male':
        formRef.current?.setFieldsValue({ note: 'Hi, man!' });
        break;
      case 'female':
        formRef.current?.setFieldsValue({ note: 'Hi, lady!' });
        break;
      case 'other':
        formRef.current?.setFieldsValue({ note: 'Hi there!' });
        break;
      default:
        break;
    }
  };

  const onFinish = (values: any) => {
    console.log(values);
  };

  const onReset = () => {
    formRef.current?.resetFields();
  };

  const onFill = () => {
    formRef.current?.setFieldsValue({ note: 'Hello world!', gender: 'male' });
  };

  return (
    <Form
      {...layout}
      ref={formRef}
      name="control-ref"
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
    >
      <Form.Item name="note" label="Note" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item name="gender" label="Gender" rules={[{ required: true }]}>
        <Select
          placeholder="Select a option and change input text above"
          onChange={onGenderChange}
          allowClear
        >
          <Option value="male">male</Option>
          <Option value="female">female</Option>
          <Option value="other">other</Option>
        </Select>
      </Form.Item>
      <Form.Item
        noStyle
        shouldUpdate={(prevValues, currentValues) => prevValues.gender !== currentValues.gender}
      >
        {({ getFieldValue }) =>
          getFieldValue('gender') === 'other' ? (
            <Form.Item name="customizeGender" label="Customize Gender" rules={[{ required: true }]}>
              <Input />
            </Form.Item>
          ) : null
        }
      </Form.Item>
      <Form.Item {...tailLayout}>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
        <Button htmlType="button" onClick={onReset}>
          Reset
        </Button>
        <Button type="link" htmlType="button" onClick={onFill}>
          Fill form
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;
#components-form-demo-control-ref .ant-btn {
  margin-right: 8px;
}

Form Layout

There are three layout for form: horizontal, vertical, inline.

TypeScript
JavaScript
import React, { useState } from 'react';
import { Button, Form, Input, Radio } from 'antd';

type LayoutType = Parameters<typeof Form>[0]['layout'];

const App: React.FC = () => {
  const [form] = Form.useForm();
  const [formLayout, setFormLayout] = useState<LayoutType>('horizontal');

  const onFormLayoutChange = ({ layout }: { layout: LayoutType }) => {
    setFormLayout(layout);
  };

  const formItemLayout =
    formLayout === 'horizontal' ? { labelCol: { span: 4 }, wrapperCol: { span: 14 } } : null;

  const buttonItemLayout =
    formLayout === 'horizontal' ? { wrapperCol: { span: 14, offset: 4 } } : null;

  return (
    <Form
      {...formItemLayout}
      layout={formLayout}
      form={form}
      initialValues={{ layout: formLayout }}
      onValuesChange={onFormLayoutChange}
      style={{ maxWidth: 600 }}
    >
      <Form.Item label="Form Layout" name="layout">
        <Radio.Group value={formLayout}>
          <Radio.Button value="horizontal">Horizontal</Radio.Button>
          <Radio.Button value="vertical">Vertical</Radio.Button>
          <Radio.Button value="inline">Inline</Radio.Button>
        </Radio.Group>
      </Form.Item>
      <Form.Item label="Field A">
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item label="Field B">
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item {...buttonItemLayout}>
        <Button type="primary">Submit</Button>
      </Form.Item>
    </Form>
  );
};

export default App;

Form disabled

Set component disabled, only works for antd components.

  InputNumber,
  TreeSelect,
  Switch,
  Checkbox,
  Upload,
} from 'antd';

const { RangePicker } = DatePicker;
const { TextArea } = Input;

const FormDisabledDemo: React.FC = () => {
  const [componentDisabled, setComponentDisabled] = useState<boolean>(true);

  return (
    <>
      <Checkbox
        checked={componentDisabled}
        onChange={(e) => setComponentDisabled(e.target.checked)}
      >
        Form disabled
      </Checkbox>
      <Form
        labelCol={{ span: 4 }}
        wrapperCol={{ span: 14 }}
        layout="horizontal"
        disabled={componentDisabled}
        style={{ maxWidth: 600 }}
      >

  );
};

export default () => <FormDisabledDemo />;

import { Button, Form, Input, Radio } from 'antd';

type RequiredMark = boolean | 'optional';

const App: React.FC = () => {

Form size

Set component size, only works for antd components.

TypeScript
JavaScript
import React, { useState } from 'react';
import {
  Button,
  Cascader,
  DatePicker,
  Form,
  Input,
  InputNumber,
  Radio,
  Select,
  Switch,
  TreeSelect,
} from 'antd';

type SizeType = Parameters<typeof Form>[0]['size'];

const App: React.FC = () => {

      <Form.Item label="Button">
        <Button>Button</Button>
      </Form.Item>
    </Form>
  );
};

export default App;

label can wrap

Turn on labelWrap to wrap label if text is long.

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input } from 'antd';

const App: React.FC = () => (
  <Form
    name="wrap"
    labelCol={{ flex: '110px' }}
    labelAlign="left"
    labelWrap
    wrapperCol={{ flex: 1 }}
    colon={false}
    style={{ maxWidth: 600 }}
  >
    <Form.Item label="正常标签文案" name="username" rules={[{ required: true }]}>
      <Input />
    </Form.Item>

    <Form.Item label="超长标签文案超长标签文案" name="password" rules={[{ required: true }]}>
      <Input />
    </Form.Item>

    <Form.Item label=" ">
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

No block rule

rule with warningOnly will not block form submit.

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, message, Space } from 'antd';

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onFinish = () => {
    message.success('Submit success!');
  };

  const onFinishFailed = () => {
    message.error('Submit failed!');
  };

  const onFill = () => {
    form.setFieldsValue({
      url: 'https://taobao.com/',
    });
  };

  return (
    <Form
      form={form}
      layout="vertical"
      onFinish={onFinish}
      onFinishFailed={onFinishFailed}
      autoComplete="off"
    >
      <Form.Item
        name="url"
        label="URL"
        rules={[{ required: true }, { type: 'url', warningOnly: true }, { type: 'string', min: 6 }]}
      >
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item>
        <Space>
          <Button type="primary" htmlType="submit">
            Submit
          </Button>
          <Button htmlType="button" onClick={onFill}>
            Fill
          </Button>
        </Space>
      </Form.Item>
    </Form>
  );
};

export default App;

Watch Hooks

useWatch helps watch the field change and only re-render for the value change. API Ref.

TypeScript
JavaScript
import React from 'react';
import { Form, Input, InputNumber, Typography } from 'antd';

const Demo: React.FC = () => {
  const [form] = Form.useForm<{ name: string; age: number }>();
  const nameValue = Form.useWatch('name', form);

  return (
    <>
      <Form form={form} layout="vertical" autoComplete="off">
        <Form.Item name="name" label="Name (Watch to trigger rerender)">
          <Input />
        </Form.Item>
        <Form.Item name="age" label="Age (Not Watch)">
          <InputNumber />
        </Form.Item>
      </Form>

      <Typography>
        <pre>Name Value: {nameValue}</pre>
      </Typography>
    </>
  );
};

export default Demo;

Path Prefix

In some scenarios, you may want to set a prefix for some fields consistently. You can achieve this effect with HOC.

TypeScript
JavaScript
import React from 'react';
import { Form, Input, Button } from 'antd';
import type { FormItemProps } from 'antd';

const MyFormItemContext = React.createContext<(string | number)[]>([]);

interface MyFormItemGroupProps {
  prefix: string | number | (string | number)[];
  children: React.ReactNode;
}

function toArr(str: string | number | (string | number)[]): (string | number)[] {
  return Array.isArray(str) ? str : [str];
}

Dynamic Form Item

Add or remove form items dynamically. add function support config initial value.

TypeScript
JavaScript
import React from 'react';

complex form control

This demo shows how to use Form.Item with multiple controls. <Form.Item name="field" /> will only bind the control(Input/Select) which is the only children of it. Imagine this case: you added some text description after the Input, then you have to wrap the Input by an extra <Form.Item name="field">. style property of Form.Item could be useful to modify the nested form item layout, or use <Form.Item noStyle /> to turn it into a pure form-binded component(like getFieldDecorator in 3.x).

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, Select, Space, Tooltip, Typography } from 'antd';

const { Option } = Select;

const onFinish = (values: any) => {
  console.log('Received values of form: ', values);
};

const App: React.FC = () => (
  <Form
    name="complex-form"
    onFinish={onFinish}
    labelCol={{ span: 8 }}
    wrapperCol={{ span: 16 }}
    style={{ maxWidth: 600 }}
  >
    <Form.Item label="Username">
      <Space>
        <Form.Item
          name="username"
          noStyle
          rules={[{ required: true, message: 'Username is required' }]}
        >
          <Input style={{ width: 160 }} placeholder="Please input" />
        </Form.Item>
        <Tooltip title="Useful information">
          <Typography.Link href="#API">Need Help?</Typography.Link>
        </Tooltip>
      </Space>
    </Form.Item>
    <Form.Item label="Address">
      <Input.Group compact>
        <Form.Item

Customized Form Controls

Customized or third-party form controls can be used in Form, too. Controls must follow these conventions:

It has a controlled property value or other name which is equal to the value of valuePropName.

It has event onChange or an event which name is equal to the value of trigger.

TypeScript
JavaScript
import React, { useState } from 'react';
import { Button, Form, Input, Select } from 'antd';

const { Option } = Select;

type Currency = 'rmb' | 'dollar';

interface PriceValue {
  number?: number;
  currency?: Currency;
}

interface PriceInputProps {
  value?: PriceValue;
  onChange?: (value: PriceValue) => void;
}

const PriceInput: React.FC<PriceInputProps> = ({ value = {}, onChange }) => {
  const [number, setNumber] = useState(0);
  const [currency, setCurrency] = useState<Currency>('rmb');

  const triggerChange = (changedValue: { number?: number; currency?: Currency }) => {
    onChange?.({ number, currency, ...value, ...changedValue });
  };

  const onNumberChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const newNumber = parseInt(e.target.value || '0', 10);
    if (Number.isNaN(number)) {
      return;
    }
    if (!('number' in value)) {
      setNumber(newNumber);
    }
    triggerChange({ number: newNumber });
  };

  const onCurrencyChange = (newCurrency: Currency) => {
    if (!('currency' in value)) {
      setCurrency(newCurrency);
    }
    triggerChange({ currency: newCurrency });
  };

  return (
    <span>
      <Input
        type="text"
        value={value.number || number}
        onChange={onNumberChange}
        style={{ width: 100 }}
      />
      <Select
        value={value.currency || currency}
        style={{ width: 80, margin: '0 8px' }}
        onChange={onCurrencyChange}
      >
        <Option value="rmb">RMB</Option>
        <Option value="dollar">Dollar</Option>
      </Select>
    </span>
  );
};

const App: React.FC = () => {
  const onFinish = (values: any) => {
    console.log('Received values from form: ', values);
  };

  const checkPrice = (_: any, value: { number: number }) => {
    if (value.number > 0) {
      return Promise.resolve();
    }
    return Promise.reject(new Error('Price must be greater than zero!'));
  };

  return (
    <Form
      name="customized_form_controls"
      layout="inline"
      onFinish={onFinish}
      initialValues={{
        price: {
          number: 0,
          currency: 'rmb',
        },
      }}
    >
      <Form.Item name="price" label="Price" rules={[{ validator: checkPrice }]}>
        <PriceInput />
      </Form.Item>
      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit

Store Form Data into Upper Component

We can store form data into upper component or Redux or dva by using onFieldsChange and fields, see more at this rc-field-form demo.

Note: Save Form data globally is not a good practice. You should avoid this if not necessary.

TypeScript
JavaScript
import React, { useState } from 'react';
import { Form, Input, Typography } from 'antd';

const { Paragraph } = Typography;

interface FieldData {
  name: string | number | (string | number)[];
  value?: any;
  touched?: boolean;
  validating?: boolean;
  errors?: string[];
}

interface CustomizedFormProps {
  onChange: (fields: FieldData[]) => void;
  fields: FieldData[];
}

const CustomizedForm: React.FC<CustomizedFormProps> = ({ onChange, fields }) => (
  <Form
    name="global_state"
    layout="inline"
    fields={fields}
    onFieldsChange={(_, allFields) => {
      onChange(allFields);
    }}

Control between forms

Use Form.Provider to process data between forms. In this case, submit button is in the Modal which is out of Form. You can use form.submit to submit form. Besides, we recommend native <Button htmlType="submit" /> to submit a form.

Form in Modal to Create

When user visit a page with a list of items, and want to create a new item. The page can popup a form in Modal, then let user fill in the form to create an item.

TypeScript
JavaScript
import React, { useState } from 'react';
import { Button, Form, Input, Modal, Radio } from 'antd';

interface Values {
  title: string;
  description: string;
  modifier: string;

  onCreate: (values: Values) => void;
  onCancel: () => void;
}

const CollectionCreateForm: React.FC<CollectionCreateFormProps> = ({

  onCreate,
  onCancel,

  const [form] = Form.useForm();
  return (
    <Modal

Time-related Controls

The value of time-related components is a dayjs object, which we need to pre-process it before we submit to server.

TypeScript
JavaScript
import React from 'react';
import { Button, DatePicker, Form, TimePicker } from 'antd';

const { RangePicker } = DatePicker;

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 8 },
  },
  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 16 },
  },
};

const config = {
  rules: [{ type: 'object' as const, required: true, message: 'Please select time!' }],
};

const rangeConfig = {
  rules: [{ type: 'array' as const, required: true, message: 'Please select time!' }],
};

const onFinish = (fieldsValue: any) => {
  // Should format date value before submit.
  const rangeValue = fieldsValue['range-picker'];
  const rangeTimeValue = fieldsValue['range-time-picker'];
  const values = {
    ...fieldsValue,
    'date-picker': fieldsValue['date-picker'].format('YYYY-MM-DD'),
    'date-time-picker': fieldsValue['date-time-picker'].format('YYYY-MM-DD HH:mm:ss'),
    'month-picker': fieldsValue['month-picker'].format('YYYY-MM'),
    'range-picker': [rangeValue[0].format('YYYY-MM-DD'), rangeValue[1].format('YYYY-MM-DD')],
    'range-time-picker': [
      rangeTimeValue[0].format('YYYY-MM-DD HH:mm:ss'),
      rangeTimeValue[1].format('YYYY-MM-DD HH:mm:ss'),
    ],
    'time-picker': fieldsValue['time-picker'].format('HH:mm:ss'),
  };
  console.log('Received values of form: ', values);
};

const App: React.FC = () => (
  <Form
    name="time_related_controls"
    {...formItemLayout}
    onFinish={onFinish}
    style={{ maxWidth: 600 }}
  >
    <Form.Item name="date-picker" label="DatePicker" {...config}>
      <DatePicker />
    </Form.Item>
    <Form.Item name="date-time-picker" label="DatePicker[showTime]" {...config}>
      <DatePicker showTime format="YYYY-MM-DD HH:mm:ss" />
    </Form.Item>
    <Form.Item name="month-picker" label="MonthPicker" {...config}>
      <DatePicker picker="month" />
    </Form.Item>
    <Form.Item name="range-picker" label="RangePicker" {...rangeConfig}>

Handle Form Data Manually

Form will collect and validate form data automatically. But if you don't need this feature or the default behavior cannot satisfy your business, you can handle form data manually.

TypeScript
JavaScript
import React, { useState } from 'react';
import { Form, InputNumber } from 'antd';

type ValidateStatus = Parameters<typeof Form.Item>[0]['validateStatus'];

const validatePrimeNumber = (
  number: number,
): {
  validateStatus: ValidateStatus;
  errorMsg: string | null;
} => {
  if (number === 11) {
    return {
      validateStatus: 'success',
      errorMsg: null,
    };
  }
  return {
    validateStatus: 'error',
    errorMsg: 'The prime between 8 and 12 is 11!',
  };
};

const formItemLayout = {
  labelCol: { span: 7 },
  wrapperCol: { span: 12 },
};

const tips =
  'A prime is a natural number greater than 1 that has no positive divisors other than 1 and itself.';

const App: React.FC = () => {
  const [number, setNumber] = useState<{
    value: number;
    validateStatus?: ValidateStatus;
    errorMsg?: string | null;
  }>({ value: 11 });

  const onNumberChange = (value: number) => {
    setNumber({
      ...validatePrimeNumber(value),
      value,
    });
  };

  return (
    <Form style={{ maxWidth: 600 }}>
      <Form.Item
        {...formItemLayout}
        label="Prime between 8 & 12"
        validateStatus={number.validateStatus}
        help={number.errorMsg || tips}
      >
        <InputNumber min={8} max={12} value={number.value} onChange={onNumberChange} />
      </Form.Item>
    </Form>
  );
};

export default App;

Customized Validation

We provide properties like validateStatus help hasFeedback to customize your own validate status and message, without using Form.

validateStatus: validate status of form components which could be 'success', 'warning', 'error', 'validating'.
hasFeedback: display feed icon of input control
help: display validate message.

TypeScript

  TimePicker,
  TreeSelect,
} from 'antd';

const { Option } = Select;

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 6 },
  },
  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 14 },
  },
};

const App: React.FC = () => (

  wrapperCol: { span: 8, offset: 4 },
};

const App: React.FC = () => {
  const [form] = Form.useForm();
  const [checkNick, setCheckNick] = useState(false);

  useEffect(() => {
    form.validateFields(['nickname']);
  }, [checkNick, form]);

  const onCheckboxChange = (e: { target: { checked: boolean } }) => {
    setCheckNick(e.target.checked);
  };

  const onCheck = async () => {

      console.log('Success:', values);
    } catch (errorInfo) {
      console.log('Failed:', errorInfo);
    }
  };

validateMessages

Form provides default verification error messages. You can modify the template by configuring validateMessages property. A common usage is to configure localization:

const validateMessages = {
  required: "'${name}' is required!",
  // ...
};

<Form validateMessages={validateMessages} />;

Besides, ConfigProvider also provides a global configuration scheme that allows for uniform configuration error notification templates:

const validateMessages = {
  required: "'${name}' is Required!",
  // ...
};

<ConfigProvider form={{ validateMessages }}>
  <Form />
</ConfigProvider>;

Form.Item

Form field component for data bidirectional binding, validation, layout, and so on.

Property	Description	Type	Default	Version
colon	Used with `label`, whether to display `:` after label text.	boolean	true
dependencies	Set the dependency field. See below	NamePath[]	-
extra	The extra prompt message. It is similar to help. Usage example: to display error message and prompt message at the same time	ReactNode	-
getValueFromEvent	Specify how to get value from event or other onChange arguments	(..args: any[]) => any	-
getValueProps	Additional props with sub component	(value: any) => any	-	4.2.0
hasFeedback	Used with `validateStatus`, this option specifies the validation status icon. Recommended to be used only with `Input`	boolean	false
help	The prompt message. If not provided, the prompt message will be generated by the validation rule.	ReactNode	-
hidden	Whether to hide Form.Item (still collect and validate value)	boolean	false	4.4.0
htmlFor	Set sub label `htmlFor`	string	-
initialValue	Config sub default value. Form `initialValues` get higher priority when conflict	string	-	4.2.0
label	Label text	ReactNode	-
labelAlign	The text align of label	`left` \| `right`	`right`
labelCol	The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>`. You can set `labelCol` on Form which will not affect nest Item. If both exists, use Item first	object	-
messageVariables	The default validate field info	Record<string, string>	-	4.7.0
name	Field name, support array	NamePath	-
normalize	Normalize value from component value before passing to Form instance. Do not support async	(value, prevValue, prevValues) => any	-
noStyle	No style for `true`, used as a pure field control	boolean	false
preserve	Keep field value even when field removed	boolean	true	4.4.0
required	Display required style. It will be generated by the validation rule	boolean	false
rules	Rules for field validation. Click here to see an example	Rule[]	-
shouldUpdate	Custom field update logic. See below	boolean \| (prevValue, curValue) => boolean	false
tooltip	Config tooltip info	ReactNode \| TooltipProps & { icon: ReactNode }	-	4.7.0
trigger	When to collect the value of children node. Click here to see an example	string	`onChange`
validateFirst	Whether stop validate on first rule of error for this field. Will parallel validate when `parallel` configured	boolean \| `parallel`	false	`parallel`: 4.5.0
validateStatus	The validation status. If not provided, it will be generated by validation rule. options: `success` `warning` `error` `validating`	string	-
validateTrigger	When to validate the value of children node	string \| string[]	`onChange`
valuePropName	Props of children node, for example, the prop of Switch is 'checked'. This prop is an encapsulation of `getValueProps`, which will be invalid after customizing `getValueProps`	string	`value`
wrapperCol	The layout for input controls, same as `labelCol`. You can set `wrapperCol` on Form which will not affect nest Item. If both exists, use Item first	object	-

After wrapped by Form.Item with name property, value(or other property defined by valuePropName) onChange(or other property defined by trigger) props will be added to form controls, the flow of form data will be handled by Form which will cause:

You shouldn't use onChange on each form control to collect data(use onValuesChange of Form), but you can still listen to onChange.
You cannot set value for each form control via value or defaultValue prop, you should set default value with initialValues of Form. Note that initialValues cannot be updated by setState dynamically, you should use setFieldsValue in that situation.
You shouldn't call setState manually, please use form.setFieldsValue to change value programmatically.

dependencies

Used when there are dependencies between fields. If a field has the dependencies prop, this field will automatically trigger updates and validations when upstream is updated. A common scenario is a user registration form with "password" and "confirm password" fields. The "Confirm Password" validation depends on the "Password" field. After setting dependencies, the "Password" field update will re-trigger the validation of "Check Password". You can refer examples.

dependencies shouldn't be used together with shouldUpdate, since it may result in conflicting update logic.

dependencies supports Form.Item with render props children since 4.5.0.

shouldUpdate

Form updates only the modified field-related components for performance optimization purposes by incremental update. In most cases, you only need to write code or do validation with the dependencies property. In some specific cases, such as when a new field option appears with a field value changed, or you just want to keep some area updating by form update, you can modify the update logic of Form.Item via the shouldUpdate.

When shouldUpdate is true, any Form update will cause the Form.Item to be re-rendered. This is very helpful for custom rendering some areas:

<Form.Item shouldUpdate>
  {() => {
    return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
  }}
</Form.Item>

You can ref example to see detail.

When shouldUpdate is a function, it will be called by form values update. Providing original values and current value to compare. This is very helpful for rendering additional fields based on values:

<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
  {() => {
    return (
      <Form.Item name="other">
        <Input />
      </Form.Item>
    );
  }}
</Form.Item>

You can ref example to see detail.

messageVariables

You can modify the default verification information of Form.Item through messageVariables.

<Form>
  <Form.Item messageVariables={{ another: 'good' }} label="user">
    <Input />
  </Form.Item>
  <Form.Item messageVariables={{ label: 'good' }} label={<span>user</span>}>
    <Input />
  </Form.Item>
</Form>

Form.List

Provides array management for fields.

Property	Description	Type	Default	Version
children	Render function	(fields: Field[], operation: { add, remove, move }, meta: { errors }) => React.ReactNode	-
initialValue	Config sub default value. Form `initialValues` get higher priority when conflict	any[]	-	4.9.0
name	Field name, support array	NamePath	-
rules	Validate rules, only support customize validator. Should work with ErrorList	{ validator, message }[]	-	4.7.0

<Form.List>
  {(fields) => (
    <div>
      {fields.map((field) => (
        <Form.Item {...field}>
          <Input />
        </Form.Item>
      ))}
    </div>
  )}
</Form.List>

Note: You should not configure Form.Item initialValue under Form.List. It always should be configured by Form.List initialValue or Form initialValues.

operation

Provide linkage between forms. If a sub form with name prop update, it will auto trigger Provider related events. See example.

Property	Description	Type	Default
onFormChange	Triggered when a sub form field updates	function(formName: string, info: { changedFields, forms })	-
onFormFinish	Triggered when a sub form submits	function(formName: string, info: { values, forms })	-

<Form.Provider
  onFormFinish={(name) => {
    if (name === 'form1') {

  values:
    {
      username: 'username',
      password: 'password',
    }
  */
  })
  .catch((errorInfo) => {
    /*
    errorInfo:
      {
        values: {
          username: 'username',
          password: 'password',
        },
        errorFields: [
          { name: ['password'], errors: ['Please input your Password!'] },
        ],
        outOfDate: false,
      }
    */
  });

Hooks

Form.useForm

type Form.useForm = (): [FormInstance]

Create Form instance to maintain data store.

Form.useFormInstance

type Form.useFormInstance = (): FormInstance

Added in 4.20.0. Get current context form instance to avoid pass as props between components:

const Sub = () => {
  const form = Form.useFormInstance();

  return <Button onClick={() => form.setFieldsValue({})} />;
};

export default () => {
  const [form] = Form.useForm();

  return (
    <Form form={form}>
      <Sub />
    </Form>
  );
};

Form.useWatch

type Form.useWatch = (namePath: NamePath, formInstance?: FormInstance): Value

Added in 4.20.0. Watch the value of a field. You can use this to interactive with other hooks like useSWR to reduce develop cost:

const Demo = () => {
  const [form] = Form.useForm();
  const userName = Form.useWatch('username', form);

  const { data: options } = useSWR(`/api/user/${userName}`, fetcher);

  return (
    <Form form={form}>
      <Form.Item name="username">
        <AutoComplete options={options} />
      </Form.Item>
    </Form>
  );
};

Form.Item.useStatus

type Form.useFormItemStatus = (): { status: ValidateStatus | undefined }

Added in 4.22.0. Could be used to get validate status of Form.Item. If this hook is not used under Form.Item, status would be undefined:

const CustomInput = ({ value, onChange }) => {
  const { status } = Form.Item.useStatus();
  return <input value={value} onChange={onChange} className={`custom-input-${status}`} />;
};

export default () => (
  <Form>
    <Form.Item name="username">
      <CustomInput />
    </Form.Item>
  </Form>
);

Difference between other data fetching method

Form only update the Field which changed to avoid full refresh perf issue. Thus you can not get real time value with getFieldsValue in render. And useWatch will rerender current component to sync with latest value. You can also use Field renderProps to get better performance if only want to do conditional render. If component no need care field value change, you can use onValuesChange to give to parent component to avoid current one rerender.

FAQ

Custom validator not working

It may be caused by your validator if it has some errors that prevents callback to be called. You can use async instead or use try...catch to catch the error:

validator: async (rule, value) => {
  throw new Error('Something wrong!');
}

// or

validator(rule, value, callback) => {
  try {
    throw new Error('Something wrong!');
  } catch (err) {
    callback(err);
  }
}

How does `name` fill value when it's an array?

name will fill value by array order. When there exists number in it and no related field in form store, it will auto convert field to array. If you want to keep it as object, use string like: ['1', 'name'].

Warning: Instance created by useForm is not connect to any Form element. Forget to pass form prop?

Before Modal opens, children elements do not exist in the view. You can set forceRender on Modal to pre-render its children. Click here to view an example.

Why is component `defaultValue` not working when inside Form.Item?

Components inside Form.Item with name property will turn into controlled mode, which makes defaultValue not work anymore. Please try initialValues of Form to set default value.

Why can not call `ref` of Form at first time?

ref only receives the mounted instance. please ref React official doc: https://reactjs.org/docs/refs-and-the-dom.html#accessing-refs

Why will `resetFields` re-mount component?

resetFields will re-mount component under Field to clean up customize component side effects (like async data, cached state, etc.). It's by design.

Difference between Form initialValues and Item initialValue?

In most case, we always recommend to use Form initialValues. Use Item initialValue only with dynamic field usage. Priority follows the rules:

Form initialValues is the first priority
Field initialValue is secondary *. Does not work when multiple Item with same name setting the initialValue

Why does `onFieldsChange` trigger three times on change when field sets `rules`?

Validating is also part of the value updating. It pass follow steps:

Trigger value change
Rule validating
Rule validated

In each onFieldsChange, you will get false > true > false with isFieldValidating.

Why doesn't Form.List support `label` and need ErrorList to show errors?

Form.List use renderProps which mean internal structure is flexible. Thus label and error can not have best place. If you want to use antd label, you can wrap with Form.Item instead.

Why can't Form.Item `dependencies` work on Form.List field?

Your name path should also contain Form.List name:

<Form.List name="users">
  {(fields) =>
    fields.map((field) => (
      <React.Fragment key={field.key}>
        <Form.Item name={[field.name, 'name']} {...someRest1} />
        <Form.Item name={[field.name, 'age']} {...someRest1} />
      </React.Fragment>
    ))
  }
</Form.List>

dependencies should be ['users', 0, 'name']

Why doesn't `normalize` support async?

React can not get correct interaction of controlled component with async value update. When user trigger onChange, component will do no response since value update is async. If you want to trigger value update async, you should use customize component to handle value state internal and pass sync value control to Form instead.

`scrollToFirstError` and `scrollToField` not working on custom form control?

See similar issues: #28370 #27994

scrollToFirstError and scrollToField deps on id attribute passed to form control, please make sure that it hasn't been ignored in your custom form control. Check codesandbox for solution.

`setFieldsValue` do not trigger `onFieldsChange` or `onValuesChange`?

It's by design. Only user interactive can trigger the change event. This design is aim to avoid call setFieldsValue in change event which may makes loop calling.
