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:

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

          )}
          trigger={['click']}>
          <a className="ant-dropdown-link"
             onClick={e => e.preventDefault()}>
            Open Dropdown
          </a>
        </Dropdown>
      </>
    </div>
  );
}
