Getting started in EJ2 TypeScript Splitter control

24 Jul 20267 minutes to read

This section explains the steps to create a simple Splitter and demonstrates the basic usage of the Splitter component using the Essential® JS 2 quickstart seed repository. This seed repository is pre-configured with the Essential® JS 2 package.

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® Splitter 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-layouts package:

npm install @syncfusion/ej2-layouts --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® Splitter 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/splitter/index.css";

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

Add Syncfusion® Splitter control to the application

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

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

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

<head>
    <title>Essential JS 2 splitter control</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
</head>

<body>
    <div id='container'>
        <!--element which is render as splitter-->
        <div id="splitter">
            <!--list of splitter panes-->
            <div></div>
            <div></div>
            <div></div>
        </div>
    </div>

</body>

</html>

Now, to render the Splitter control, add the following TypeScript code to the ~/src/app/app.ts file.

import { Splitter } from '@syncfusion/ej2-layouts';

// Initialize Splitter control
let splitObject: Splitter = new Splitter({
    height: '250px',
    width: '600px'
});

// Render initialized splitter
splitObject.appendTo('#splitter');

Load content to the pane

You can load the pane contents in either HTML element or string types using content property.

For detailed information, refer to the pane content section.

import { Splitter } from '@syncfusion/ej2-layouts';

let splitObj: Splitter = new Splitter({
    paneSettings: [
        // Content for Pane 1
        { content:'Left Pane' },

        // Content for Pane 2
        { content:'Middle Pane' },

        // Content for Pane 3
        { content:'Right Pane' }
    ],
    height: '250px'
});

splitObj.appendTo('#splitter');

Run the application

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

npm start

The below output can be achieved by following the steps mentioned above.

import { Splitter } from '@syncfusion/ej2-layouts';

// Initialize splitter control
let splitObj: Splitter = new Splitter({
    paneSettings: [
        // Content for Pane 1
        { content:'Left Pane' },

        // Content for Pane 2
        { content:'Middle Pane' },

        // Content for Pane 3
        { content:'Right Pane' }
    ],
    height: '250px'
});

// Render initialized splitter
splitObj.appendTo('#splitter');
