How to use Popper Component in ReactJS ?

A Popper is used to show the part of the content on top of another. It’s an alternative feature for react-popper. Material UI for React has this component available for us, and it is simple and very easy to integrate. For perfect positioning, it uses 3rd party library which is Popper.js.

Prerequisites:

• NodeJS or NPM
• ReactJS
• Material UI

Steps to Create the 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: Install the material-ui, emotion/react, mui/styled-engine, modules using the following command.

npm install @mui/material
npm install @emotion/react
npm install @mui/styled-engine

Project Structure:

Project Structure

package.json:

  "dependencies": {
    "@mui/material": "^5.14.18",
    "@emotion/react": "^11.11.1",
    "@mui/styled-engine": "^5.14.18",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  }

Example 1: In this example, we will create a simple Popper component that gets displayed at the click of a button. Please update your App.js file like below:

Javascript

import { Popper } from '@mui/material';
import React from 'react';

export default function App() {

    const [anchorEl, setAnchorEl] = React.useState(null);
    const open = Boolean(anchorEl);

    return (
        <div style={{ display: 'block', padding: 30 }}>
            <h1 style={{ color: 'green' }}>GeeksforGeeks</h1>
            <h4>How to use Popper Component in ReactJS?</h4>
            <button type="button" onClick={(event) => {
                setAnchorEl(anchorEl ? null : event.currentTarget);
            }}>
                Click Me to Toggle Popper
            </button>
            <Popper
                id={open ? 'simple-popper' : undefined}
                open={open}
                anchorEl={anchorEl}>
                <div style={{
                    padding: 2,
                    border: '1px solid',
                    backgroundColor: 'gray',
                }}>Greetings from GeeksforGeeks</div>
            </Popper>
        </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

Example 2: In this example, we will create 2 Popper components that get displayed in different directions, one at the top and the other at the bottom in orientation.

Javascript

import { Popper } from '@mui/material';
import React from 'react';

export default function App() {
    const [anchorElA, setAnchorElA] = React.useState(null);
    const [anchorElB, setAnchorElB] = React.useState(null);
    const openA = Boolean(anchorElA);
    const openB = Boolean(anchorElB);

    return (
        <div style={{ display: 'block', padding: 30 }}>
            <h1 style={{ color: 'green' }}>GeeksforGeeks</h1>
            <h4>How to use Popper Component in ReactJS?</h4>
            <div style=
                {
                    {
                        display: 'flex',
                        gap: '10px'
                    }
                }>
                <button type="button" onClick={(event) => {
                    setAnchorElA(anchorElA ? null : event.currentTarget);
                }}>
                    Popper on top
                </button>
                <button type="button" onClick={(event) => {
                    setAnchorElB(anchorElB ? null : event.currentTarget);
                }}>
                    Popper on bottom
                </button>
            </div>
            <Popper
                id={openA ? 'simple-popper' : undefined}
                placement='top'
                open={openA}
                anchorEl={anchorElA}>
                <div style={{
                    padding: 2,
                    border: '1px solid',
                    backgroundColor: 'gray',
                }}>
                    Greetings from GeeksforGeeks
                </div>
            </Popper>
            <Popper
                id={openB ? 'simple-popper' : undefined}
                placement='bottom'
                open={openB}
                anchorEl={anchorElB}>
                <div style={{
                    padding: 2,
                    border: '1px solid',
                    backgroundColor: 'gray',
                }}>Greetings from GeeksforGeeks</div>
            </Popper>
        </div>
    );
}
