ReactJS UI Ant Design Radio Component

Last Updated : 21 May, 2021

Ant Design Library has this component pre-built, and it is very easy to integrate as well. Radio Component allows the user to select one option from a set. We can use the following approach in ReactJS to use the Ant Design Radio Component.

Radio Methods:

blur(): This method is used to remove the focus from the element.
focus(): This method is used to get the focus on the element.

Radio Props:

autoFocus: It is used to get focus when the component is mounted.
checked: It indicates whether the radio is selected or not.
defaultChecked: It is used to specify the initial state of whether the radio is selected or not.
disabled: It is used to disable the radio.
value: It is used to denote the value for the radio button which is selected.

RadioGroup Props:

buttonStyle: It is used to denote the style type for the radio button.
defaultValue: It is used to define the default selected value for the radio button.
disabled: It is used to disable all radio buttons.
name: It is used to define the name property of all input children which are of type radio.
options: It is used to set children optional.
optionType: It is used to specify the option type for the radio.
size: It is used to denote the size of the radio.
value: It is used for setting the currently selected value.
onChange: It is the callback function which is triggered when the state changes.

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, { useState } from 'react'
import "antd/dist/antd.css"; 
import { Radio } from 'antd'; 
  
export default function App() { 
  
  const [currentValue, setCurrentValue] = useState("Goa") 
  
  return ( 
    <div style={{ display: 'block', width: 700, padding: 30 }}> 
      <h4>ReactJS Ant-Design Radio Component</h4>   
      <Radio.Group onChange={(e) => { 
        setCurrentValue(e.target.value) 
      }} value={currentValue}> 
        <Radio value={"Goa"}>Goa</Radio> 
        <Radio value={"MP"}>MP</Radio> 
        <Radio value={"Delhi"}>Delhi</Radio> 
        <Radio value={"UP"}>UP</Radio> 
      </Radio.Group> <br /> 
      Current Selected Option: {currentValue} 
    </div> 
  ); 
}
