Getting started in EJ2 TypeScript Accordion control

29 Jul 20263 minutes to read

This section briefly explains about how to create a simple Accordion using TypeScript and
configure the Accordion items using Essential® JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Prerequisites

Ensure the following tools are installed on your machine:

Set up the development environment

Clone the Syncfusion® TypeScript (Essential® JS 2) quickstart project from GitHub in the command prompt:

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack ej2-quickstart

Navigate to the project folder in the command prompt:

cd ej2-quickstart

Install Syncfusion® Accordion package

Syncfusion® TypeScript (Essential® JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion® TypeScript (Essential® JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

Use the following command to install the @syncfusion/ej2-navigations package:

npm install @syncfusion/ej2-navigations --save

Then, install the remaining dependent npm packages using the following command:

npm install

For more information about individual package and alternative installation methods, see the installation guide.

Import Syncfusion® Accordion CSS styles

Syncfusion® JavaScript controls provide built-in themes, which are available from the npm theme packages. Additionally, themes can be loaded via CDN or customized using the Theme Studio. For more information, refer to the themes documentation.

The quickstart application is preconfigured to use the Fluent2 theme. To install the Fluent2 theme package, use the following command:

npm install @syncfusion/ej2-fluent2-theme --save

The required styles are imported in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-fluent2-theme/styles/accordion/index.css";

Learn more about built-in themes and individual control CSS references.

Add Syncfusion® Accordion control to the application

Open the application in Visual Studio Code and add the Syncfusion® JavaScript UI controls.

In this article, the Accordion control is used as an example. Add the following element to the ~/src/index.html file.

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
</head>

<body>
     <div style="margin: 50px;">
        <!--element which is going to render-->
        <div id="element"></div>
    </div>
</body>

</html>

To render the Accordion control, add the following JavaScript code to the ~/src/app/app.ts file

import { Accordion } from '@syncfusion/ej2-navigations';

// Initialize Accordion component
let accordion: Accordion = new Accordion({
    items: [
      { header: 'ASP.NET', content: 'Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.' },
      { header: 'ASP.NET MVC', content: 'The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller.' },
      { header: 'JavaScript', content: '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.' },
    ]
});

// Render initialized Accordion
accordion.appendTo('#element');

Run the application

Now, run the application in the browser using the following command.

npm start

Output will be as follows:
