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 required module using the following command:
npm install antd
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 "antd/dist/antd.css"; import { Menu, Dropdown } from 'antd';   export default function App() {     return (     <div style={{       display: 'block', width: 700, padding: 30     }}>       <h4>ReactJS Ant-Design Dropdown Component</h4>       <>         <Dropdown           overlay={(             <Menu>               <Menu.Item key="0">                 Menu Item One               </Menu.Item>               <Menu.Item key="1">               Menu Item Two               </Menu.Item>               <Menu.Item key="1">               Menu Item Three               </Menu.Item>             </Menu>           )}           trigger={['click']}>           <a className="ant-dropdown-link"              onClick={e => e.preventDefault()}>             Open Dropdown           </a>         </Dropdown>       </>     </div>   ); } |
