This section explains how to create a simple Button Group and configure its available functionalities 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.jsconfiguration and uses the latest version of the webpack-cli. It requires nodev14.15.0or 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® Button Group 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-buttons package:
npm install @syncfusion/ej2-buttons --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® Button Group 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 --saveThe required styles are imported in the ~/src/styles/styles.css file, as shown below:
@import "../../node_modules/@syncfusion/ej2-fluent2-theme/styles/button-group/index.css";Learn more about built-in themes and individual control CSS references.
Add Syncfusion® Button Group control to the application
The Button group can be initialized through input tags.
Add the HTML input element which needs to be initialized as Button in index.html.
Open the application in Visual Studio Code and add the Syncfusion® TypeScript UI controls.
In this article, the Button group control is used as an example. Add the following Button group element to the ~/src/index.html file.
