As the name suggests, a tree view widget presents a hierarchical list. Material UI for React has this component available for us, and it is very easy to integrate. We can use the following approach in ReactJS to use TreeView Component.
Creating React Application And Installing Module:
Step 1: Create a React application using the following command:
npx create-react-app foldername
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
cd foldername
Step 3: After creating the ReactJS application, Install the material-ui module using the following command:
npm install @material-ui/core npm install @material-ui/lab npm install @material-ui/icons
Project Structure: It will look like the following.
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 ExpandMoreIcon from '@material-ui/icons/ExpandMore'; import ChevronRightIcon from '@material-ui/icons/ChevronRight'; import TreeItem from '@material-ui/lab/TreeItem'; import TreeView from '@material-ui/lab/TreeView'; export default function App() { return ( <div style={{ display: 'block', padding: 30 }}> <h4>How to use TreeView Component in ReactJS?</h4> <TreeView style={{ height: 240, maxWidth: 400, flexGrow: 1, }} defaultExpandIcon={<ChevronRightIcon />} defaultCollapseIcon={<ExpandMoreIcon />} > <TreeItem nodeId="0" label="States"> <TreeItem nodeId="1" label="Madhya Pradesh" /> <TreeItem nodeId="2" label="Goa" /> <TreeItem nodeId="3" label="Delhi" /> <TreeItem nodeId="4" label="Mumbai, etc" /> </TreeItem> </TreeView> </div> ); } |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
