React MUI RadioGroup API

React MUI is a UI library providing predefined robust and customizable components for React for easier web development. The MUI design is based on top of Material Design by Google. Material-UI is a user interface library that provides predefined and customizable React components for faster and easy web development, these Material-UI components are based on top of Material Design by Google.  

In this article, we are going to discuss the React MUI RadioGroup API. RadioGroup is used to show different radio button options for users to choose from. Users can select among them as per their choice. 

Import RadioGroup  API:

import RadioGroup  from '@mui/material/RadioGroup'

Props list:

• children: It is used to denote the content of RadioGroup.
• defaultValue: It is used to set a default value of the RadioGroup.
• name: Used to reference the radio button. 
• value: The value of the selected radio button is shown through this.
• onChange: Callback function to access current event value and perform other actions on user click.

Approach: Let us create a React project and install React MUI module. Then we will create a UI that will showcase React MUI RadioGroup API.

Creating React Project:

Step 1: To create a react app, you need to install react modules through npx command. “npx” is used instead of “npm” because you will be needing this command in your app’s lifecycle only once.

npx create-react-app project_name

Step 2: After creating your react project, move into the folder to perform different operations.

cd project_name

Step 3: After creating the ReactJS application, Install the required module using the following command:

npm install @mui/material @emotion/react @emotion/styled
npm install @mui/lab

Project Structure: After running the commands mentioned in the above steps, if you open the project in an editor you can see a similar project structure as shown below. The new component user makes or the code changes, we will be performing will be done in the source folder.

Project Structure

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Example 1: We are creating a UI that shows React MUI RadioGroup API.

App.js

import * as React from 'react';
import Radio from '@mui/material/Radio';
import RadioGroup from '@mui/material/RadioGroup';
import FormControlLabel from '@mui/material/FormControlLabel';
import FormControl from '@mui/material/FormControl';
import FormLabel from '@mui/material/FormLabel';

export default function Demo() {
    return (
        <div style={{ margin: 100 }}>
            <h1 style={{ color: 'green' }}>GeeksforGeeks</h1>
            <h3><u>React MUI RadioGroup API  </u></h3><br />
            <FormControl>
                <FormLabel>Favourite GFG Course</FormLabel><br />
                <RadioGroup row>
                    <FormControlLabel value=
                        "DSA Self Paced Course"
                        control={<Radio />}
                        label="DSA Self Paced Course" />
                    <FormControlLabel value=
                        "Amazon SDE Preparation"
                        control={<Radio />}
                        label="Amazon SDE Preparation" />
                    <FormControlLabel value="other"
                        control={<Radio />}
                        label="Other" />
                </RadioGroup>
            </FormControl>
        </div>
    );
}

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:

                    Radio Buttons Group
                </FormLabel>
                <RadioGroup

                        control={<Radio />}
                        label="Choice 2" />
                    <FormControlLabel value="Choice 3"
                        control={<Radio color="secondary" />}
                        label="Choice 3" />
                </RadioGroup>
            </FormControl>
        </div>
    );
}

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
