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.

The most basic usage.

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

const treeData = [
  {
    value: 'parent 1',
    title: 'parent 1',
    children: [
      {
        value: 'parent 1-0',
        title: 'parent 1-0',
        children: [
          {
            value: 'leaf1',
            title: 'leaf1',
          },
          {
            value: 'leaf2',
            title: 'leaf2',
          },
        ],
      },
      {
        value: 'parent 1-1',
        title: 'parent 1-1',

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.

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

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',
  },
];

const App: React.FC = () => {
  const [value, setValue] = useState<string>();

  const onChange = (newValue: string) => {
    console.log(newValue);
    setValue(newValue);
  };

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