21 Feb 20246 minutes to read
This section explains how to create a simple Split button, and configure its available functionalities in TypeScript, 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 nodev14.15.0
or higher. For more information about webpack and its features, refer to the webpack documentation.
Dependencies
The list of dependencies required to use the SplitButton component in your application is given as follows:
|-- @syncfusion/ej2-splitbuttons
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttons
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
To render SplitButton component, need to import Button and its dependent components styles as given below in the ~/src/styles/styles.css
file, as shown below:
@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";
Add SplitButton to the project
Add the HTML Button tag with ID attribute as the element
to your index.html
file.

<body>
<div>
<!--Element which is going to render-->
<button id="element">Paste</button>
</div>
</body>
</html>
Then, import the SplitButton component in your app.ts
file, and initialize it with the #element
.
[src/app/app.ts]
import { SplitButton, ItemModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
//Initialize action items.
let items: ItemModel[] = [
{ text: 'Cut'},
{ text: 'Copy'},
{ text: 'Paste'}
];
// Initialize the SplitButton component.
let splitBtn: SplitButton = new SplitButton({ items: items });
// Render initialized SplitButton.
splitBtn.appendTo('#element');
Run the application
Run the application in the browser using the following command:
npm start
The following example shows a basic SplitButton component.
import { SplitButton, ItemModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
//Initialize action items.
let items: ItemModel[] = [
{ text: 'Cut'},
{ text: 'Copy'},
{ text: 'Paste'}
];
// Initialize the SplitButton component.
let splitBtn: SplitButton = new SplitButton({ items: items });
// Render initialized SplitButton.
splitBtn.appendTo('#element');
