React-Bootstrap is a front-end framework that was designed keeping react in mind. Accordion Component provides a way to control our card components so that we can open them one at a time. We can use the following approach in ReactJS to use the react-bootstrap Accordion Component.
Accordion Props:
- activeKey: It is the currently active key which corresponds to the expanded card which is currently active.
- as: It can be used as a custom element type for this component.
- defaultActiveKey: It is the default active key that expands on start.
- onSelect: It is the callback function named as SelectCallback.
- bsPrefix: It is an escape hatch for working with strongly customized bootstrap CSS.
Accordion.Toggle Props:
- as: It can be used as a custom element type for this component.
- eventKey: It is a key that is used to correspond to the collapse component when the click is triggered on this component.
- onClick: It is the callback function that is triggered when this component is clicked.
Accordion.Collapse Props:
- children: It is used to pass the children’s prop which should contain only a single child.
- eventKey: It is a key that is used to correspond to the toggler.
useAccordionToggle Props: It is used to create our custom toggle component with this hook.
- eventKey: It is the key that is given for the specified element/card.
- callback: It is a callback function that is triggered on a toggle event.
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. folder name, 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 react-bootstrap npm install bootstrap
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 'bootstrap/dist/css/bootstrap.css'; import Accordion from 'react-bootstrap/Accordion'; import Card from 'react-bootstrap/Card'; import Button from 'react-bootstrap/Button'; export default function App() { return ( <div style={{ display: 'block', width: 700, padding: 30 }}> <h4>React-Bootstrap Accordion Component</h4> <Accordion defaultActiveKey="0"> <Card> <Card.Header> <Accordion.Toggle as={Button} variant="link" eventKey="0"> Click Me to Toggle! </Accordion.Toggle> </Card.Header> <Accordion.Collapse eventKey="0"> <Card.Body> Greetings from neveropen </Card.Body> </Accordion.Collapse> </Card> </Accordion> </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/, you will see the following output:
