Getting started in EJ2 TypeScript Splitter control

3 Feb 20247 minutes to read

This section explains how to create a simple Splitter component and configure its available functionalities, using the 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.

Dependencies

The following list of dependencies required to use the splitter control in your application:

|-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-base

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

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

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

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

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion CSS styles

The Splitter CSS files are available in the ej2-layouts package folder. This can be referenced in the ~/src/styles/styles.css file of your application using the following code.

@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-layouts/styles/material.css';

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls.
This web tool is useful to combine the required control scripts and styles in a single file.

Adding splitter to the project

The splitter can be initialized through div tag with child elements. Add the div element with the id attribute #splitter inside the body tag in your index.html.

[src/index.html]

<!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, import the splitter control to your app.ts and initialize it to the element #splitter as follows.

[src/app/app.ts]

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';

// 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');

Run the application

After completing the configuration to render the splitter, run the following command to display
the output in your default browser.

npm run start

The following example illustrates the output in your browser.

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');
