Transfer

Double column transfer choice box.

When To Use#

  • It is a select control essentially which can be use for selecting multiple items.

  • Transfer can display more information for items and take up more space.

Transfer the elements between two columns in an intuitive and efficient way.

One or more elements can be selected from either column, one click on the proper direction button, and the transfer is done. The left column is considered the source and the right column is considered the target. As you can see in the API description, these names are reflected in.

The most basic usage of Transfer involves providing the source data and target keys arrays, plus the rendering and some callback functions.

Advanced Usage of Transfer.

You can customize the labels of the transfer buttons, the width and height of the columns, and what should be displayed in the footer.

  state = {
    mockData: [],

        key: i.toString(),
        title: `content${i + 1}`,
        description: `description of content${i + 1}`,
        chosen: Math.random() * 2 > 1,
      };
      if (data.chosen) {
        targetKeys.push(data.key);
      }
      mockData.push(data);
    }
    this.setState({ mockData, targetKeys });
  };

  handleChange = targetKeys => {
    this.setState({ targetKeys });
  };

  renderFooter = () => (
    <Button size="small" style={{ float: 'right', margin: 5 }} onClick={this.getMock}>
      reload

renderThe function to generate the item shown on a column. Based on an record (element of the dataSource array), this function should return a React element which is generated from that record. Also, it can return a plain object with value and label, label is a React element and value is for title(record) => ReactNode-

Render Props#

Transfer accept children to customize render list, using follow props:

PropertyDescriptionTypeVersion
directionList render directionleft | right
disabledDisable list or notboolean
filteredItemsFiltered itemsTransferItem[]
onItemSelectSelect item(key: string, selected: boolean)
onItemSelectAllSelect a group of items(keys: string[], selected: boolean)
selectedKeysSelected itemsstring[]

example#

<Transfer {...props}>{listProps => <YourComponent {...listProps} />}</Transfer>

Warning#

According the standard of React, the key should always be supplied directly to the elements in the array. In Transfer, the keys should be set on the elements included in dataSource array. By default, key property is used as an unique identifier.

If there's no key in your data, you should use rowKey to specify the key that will be used for uniquely identify each element.

// eg. your primary key is `uid`
return <Transfer rowKey={record => record.uid} />;
