This section briefly explains you the steps required to create a simple React Accordion and demonstrate the basic usage of the Accordion control.

Dependencies

The following list of dependencies are required to use the React Accordion component in your application.

|-- @syncfusion/ej2-react-navigations
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-react-base
    |-- @syncfusion/ej2-navigations
        |-- @syncfusion/ej2-buttons
        |-- @syncfusion/ej2-popups

Setup for Local Development

To easily set up a React application, use create-vite-app, which provides a faster development environment, smaller bundle sizes, and optimized builds compared to traditional tools like create-react-app. For detailed steps, refer to the Vite installation instructions. Vite sets up your environment using JavaScript and optimizes your application for production.

Note: To create a React application using create-react-app, refer to this documentation for more details.

To create a new React application, run the following command.

npm create vite@latest my-app

To set-up a React application in TypeScript environment, run the following command.

npm create vite@latest my-app -- --template react-ts
cd my-app
npm run dev

To set-up a React application in JavaScript environment, run the following command.

npm create vite@latest my-app -- --template react
cd my-app
npm run dev

Adding Syncfusion® packages

All the available Essential® JS 2 packages are published in npmjs.com public registry.
To install Accordion component, use the following command

npm install @syncfusion/ej2-react-navigations --save

Adding CSS reference

Add components style as given below in src/App.css.

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-react-navigations/styles/material.css';

To refer App.css in the application then import it in the src/App.tsx file.

Initialize the Accordion using Items

The React Accordion can be rendered by defining an array of items.

  • Import the Accordion component to your src/App.tsx file using following code.
import { AccordionComponent, AccordionItemDirective, AccordionItemsDirective } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';

const ReactApp = () => {
  const aspContent = () => {
    return (<div>
      Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.
    </div>);
  }

  const mvcContent = () => {
    return (<div>
      The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller.
    </div>);
  }

  const jsContent = () => {
    return (<div>
      JavaScript (JS) is an interpreted computer programming language.It was originally implemented as part of web browsers so that client-side scripts could interact with the user, control the browser, communicate asynchronously, and alter the document content that was displayed.
    </div>);
  }

  return (
    <AccordionComponent>
      <AccordionItemsDirective>
        <AccordionItemDirective header='ASP.NET' content={aspContent} />
        <AccordionItemDirective header='ASP.NET MVC' content={mvcContent} />
        <AccordionItemDirective header='JavaScript' content={jsContent} />
      </AccordionItemsDirective>
    </AccordionComponent>
  );
}
export default ReactApp;

Now run the npm run dev command in the console to start the development server. This command compiles your code and serves the application locally, opening it in the browser.

npm run dev

In the above sample code, #element is the id of the HTML element in a page to which the Accordion is initialized.

Initialize the Accordion using HTML elements

The React Accordion component can be rendered based on the given HTML element using id as target property.
You need to follow the below structure of HTML elements to render the Accordion.

  <div id='accordion_html_markup'>   --> Root Accordion Element
       <div>      --> Accordion Item Container
            <div>   --> Accordion Header Container
                <div> </div> --> Accordion Header
            </div>
            <div>  --> Accordion Panel Container
                <div> </div> --> Accordion Content
             </div>
        </div>
  </div>

import { AccordionComponent } from '@syncfusion/ej2-react-navigations';
import * as React from "react";
import * as ReactDOM from "react-dom";

const ReactApp = () => {
    return (<AccordionComponent>
      <div>
        <div>
          <div> ASP.NET </div>
        </div>
        <div>
          <div>
            Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.
          </div>
        </div>
      </div>
      <div>
        <div>
          <div> ASP.NET MVC </div>
        </div>
        <div>
          <div>
            The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller.
          </div>
        </div>
      </div>
      <div>
        <div>
          <div> JavaScript </div>

        <div>
          <div>

          </div>
        </div>
      </div>
    </AccordionComponent>);
}
const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<ReactApp />);
import { AccordionComponent } from '@syncfusion/ej2-react-navigations';
import * as React from "react";
import * as ReactDOM from "react-dom";

const ReactApp = () => {
  return (
    <AccordionComponent>
      <div>
        <div>
          <div> ASP.NET </div>
        </div>
        <div>
          <div>
            Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.

          <div> JavaScript </div>

          </div>
        </div>

const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<ReactApp />);
