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 set-up a React application, choose any of the following ways. The best and easiest way is to use the create-react-app. It sets up your development environment in JavaScript and improvise your application for production. Refer to the installation instructions of create-react-app.

npx create-react-app my-app
cd my-app
npm start

or

yarn create react-app my-app
cd my-app
yarn start

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

npx create-react-app my-app --template typescript
cd my-app
npm start

Besides using the npm package runner tool, also create an application from the npm init. To begin with the npm init, upgrade the npm version to npm 6+.

npm init react-app my-app
cd my-app
npm start

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.ts 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.ts 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;
  • Run the application in the browser using the following command.
npm start

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> ASP.NET </div>
        </div>
        <div>
