Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'

import 'rsuite/dist/styles/rsuite-default.css'; 

import { TreePicker } from 'rsuite'; 

export default function App() { 

  // Sample Options 

  const options = [ 

    { 

      "label": "Madhya Pradesh", 

      "value": 1, 

      "children": [ 

        {
