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

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"

        onChange={this.onChange}

        <TreeNode value="parent 1" title="parent 1">
          <TreeNode value="parent 1-0" title="parent 1-0">
            <TreeNode value="leaf1" title="my leaf" />
            <TreeNode value="leaf2" title="your leaf" />
          </TreeNode>
          <TreeNode value="parent 1-1" title="parent 1-1">
            <TreeNode value="sss" title={<b style={{ color: '#08c' }}>sss</b>} />
          </TreeNode>
        </TreeNode>
      </TreeSelect>
    );
  }
}

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

expand codeexpand code
import { TreeSelect } from 'antd';

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

        onChange={this.onChange}

Asynchronous loading tree node.

            this.genTreeNode(id, false),
            this.genTreeNode(id, true),
          ]),
        });
        resolve();
      }, 300);
    });

  onChange = value => {
