TreeSelect

Tree selection control.

When To Use#

TreeSelect is similar to Select, but the values are provided in a tree like structure. Any data whose entries are defined in a hierarchical manner is fit to use this control. Examples of such case may include a corporate hierarchy, a directory structure, and so on.

Examples

Basic

The most basic usage.

import { TreeSelect } from 'antd';

const { TreeNode } = TreeSelect;

class Demo extends React.Component {
  state = {
    value: undefined,
  };

  onChange = value => {
    console.log(value);
    this.setState({ value });
  };

  render() {
    return (
      <TreeSelect
        showSearch
        style={{ width: '100%' }}
        value={this.state.value}
        dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
        placeholder="Please select"
        allowClear
        treeDefaultExpandAll
        onChange={this.onChange}
      >
        <TreeNode value="parent 1" title="parent 1" key="0-1">
          <TreeNode value="parent 1-0" title="parent 1-0" key="0-1-1">
            <TreeNode value="leaf1" title="my leaf" key="random" />
            <TreeNode value="leaf2" title="your leaf" key="random1" />
          </TreeNode>
          <TreeNode value="parent 1-1" title="parent 1-1" key="random2">
            <TreeNode value="sss" title={<b style={{ color: '#08c' }}>sss</b>} key="random3" />
          </TreeNode>
        </TreeNode>
      </TreeSelect>
    );
  }
}

ReactDOM.render(<Demo />, mountNode);

Generate from tree data

The tree structure can be populated using treeData property. This is a quick and easy way to provide the tree content.

import { TreeSelect } from 'antd';

const treeData = [
  {
    title: 'Node1',
    value: '0-0',
    key: '0-0',
    children: [
      {
        title: 'Child Node1',
        value: '0-0-1',
        key: '0-0-1',
      },
      {
        title: 'Child Node2',
        value: '0-0-2',
        key: '0-0-2',
      },
    ],
  },
  {
    title: 'Node2',
    value: '0-1',
    key: '0-1',
  },
];

class Demo extends React.Component {
  state = {
    value: undefined,
  };

  onChange = value => {
    console.log(value);
    this.setState({ value });
  };

  render() {
    return (
      <TreeSelect
        style={{ width: '100%' }}
        value={this.state.value}
        dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
        treeData={treeData}
        placeholder="Please select"
        treeDefaultExpandAll
        onChange={this.onChange}
      />
    );
  }
}

ReactDOM.render(<Demo />, mountNode);

Asynchronous loading

Asynchronous loading tree node.

import { TreeSelect } from 'antd';

class Demo extends React.Component {
  state = {
    value: undefined,
    treeData: [
      { id: 1, pId: 0, value: '1', title: 'Expand to load' },
      { id: 2, pId: 0, value: '2', title: 'Expand to load' },
      { id: 3, pId: 0, value: '3', title: 'Tree Node', isLeaf: true },
    ],
  };

  genTreeNode = (parentId, isLeaf = false) => {
    const random = Math.random()
      .toString(36)
      .substring(2, 6);
    return {
      id: random,
      pId: parentId,
      value: random,
      title: isLeaf ? 'Tree Node' : 'Expand to load',
      isLeaf,
    };
  };

  onLoadData = treeNode =>
    new Promise(resolve => {
      const { id } = treeNode.props;
      setTimeout(() => {
        this.setState({
          treeData: this.state.treeData.concat([
            this.genTreeNode(id, false),
            this.genTreeNode(id, true),
          ]),
        });
        resolve();
      }, 300);
    });

  onChange = value => {
    console.log(value);
    this.setState({ value });
  };

  render() {
    const { treeData } = this.state;
    return (
      <TreeSelect
        treeDataSimpleMode
        style={{ width: '100%' }}
        value={this.state.value}
        dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
        placeholder="Please select"
        onChange={this.onChange}
        loadData={this.onLoadData}
        treeData={treeData}
      />
    );
  }
}

ReactDOM.render(<Demo />, mountNode);

Multiple Selection

Multiple selection usage.

import { TreeSelect } from 'antd';

const { TreeNode } = TreeSelect;

class Demo extends React.Component {
  state = {
    value: undefined,
  };

  onChange = value => {
    console.log(value);
    this.setState({ value });
  };

  render() {
    return (
      <TreeSelect
        showSearch
        style={{ width: '100%' }}
        value={this.state.value}
        dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
        placeholder="Please select"
        allowClear
        multiple
        treeDefaultExpandAll
        onChange={this.onChange}
      >
        <TreeNode value="parent 1" title="parent 1" key="0-1">
          <TreeNode value="parent 1-0" title="parent 1-0" key="0-1-1">
            <TreeNode value="leaf1" title="my leaf" key="random" />
            <TreeNode value="leaf2" title="your leaf" key="random1" />
          </TreeNode>
          <TreeNode value="parent 1-1" title="parent 1-1" key="random2">
            <TreeNode value="sss" title={<b style={{ color: '#08c' }}>sss</b>} key="random3" />
          </TreeNode>
        </TreeNode>
      </TreeSelect>
    );
  }
}

ReactDOM.render(<Demo />, mountNode);

Checkable

Multiple and checkable.

import { TreeSelect } from 'antd';

const { SHOW_PARENT } = TreeSelect;

const treeData = [
  {
    title: 'Node1',
    value: '0-0',
    key: '0-0',
    children: [
      {
        title: 'Child Node1',
        value: '0-0-0',
        key: '0-0-0',
      },
    ],
  },
  {
    title: 'Node2',
    value: '0-1',
    key: '0-1',
    children: [
      {
        title: 'Child Node3',
        value: '0-1-0',
        key: '0-1-0',
      },
      {
        title: 'Child Node4',
        value: '0-1-1',
        key: '0-1-1',
      },
      {
        title: 'Child Node5',
        value: '0-1-2',
        key: '0-1-2',
      },
    ],
  },
];

class Demo extends React.Component {
  state = {
    value: ['0-0-0'],
  };

  onChange = value => {
    console.log('onChange ', value);
    this.setState({ value });
  };

  render() {
    const tProps = {
      treeData,
      value: this.state.value,
      onChange: this.onChange,
      treeCheckable: true,
      showCheckedStrategy: SHOW_PARENT,
      searchPlaceholder: 'Please select',
      style: {
        width: '100%',
      },
    };
    return <TreeSelect {...tProps} />;
  }
}

ReactDOM.render(<Demo />, mountNode);

TreeNode props#

We recommend you to use treeData rather than TreeNode, to avoid the trouble of manual construction.
