How to Add Radio Buttons in React JS

Radio buttons are a common element in web forms, allowing users to select one option from a predefined set. Implementing radio buttons in a React JS application is straightforward. This guide will walk you through the process step-by-step.

Setting Up Your React Environment

Before we dive into the implementation, ensure you have a React application set up. If you don't have one yet, you can create a new React app using Create React App:

Basic Radio Button Implementation

Step 1: Create a Functional Component

First, create a functional component where you'll add the radio buttons. For this example, we'll create a RadioButtonGroup component.

Explanation

State Management: We use the useState hook to manage the state of the selected radio button. The selectedOption state variable holds the value of the currently selected option.

Handling Changes: The handleOptionChange function updates the state whenever a different radio button is selected.

Radio Button Elements: Each radio button is implemented as an input element of type radio. The checked attribute is used to determine if the button is the currently selected one, and the onChange attribute specifies the function to call when the radio button's state changes.

Displaying the Selected Option: The currently selected option is displayed below the form using the selectedOption state variable.

Styling the Radio Buttons

To style the radio buttons, you can add CSS to your project. Create a CSS file (e.g., RadioButtonGroup.css) and import it into your RadioButtonGroup component.
