3 Nov 20238 minutes to read

This section explains how to create a simple ButtonGroup, and configure its available functionalities by 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 are required to use the ButtonGroup component in your application.

|-- @syncfusion/ej2-splitbuttons

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

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

Add ButtonGroup to the project

Add the HTML div tag with class name as e-btn-group and the button elements that should group inside the div element with class name as
e-btn to your index.html file.

#container {

}
.e-btn-group {

}

Orientation

ButtonGroup can be arranged in a vertical and horizontal orientation. By default, it is horizontally aligned.

Vertical Orientation

ButtonGroup can be aligned vertically by using the built-in CSS class e-vertical to the target element.

The following example illustrates how to achieve vertical orientation in ButtonGroup.

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

<head>
    <title>EJ2 Button-Group</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Typescript UI Controls" />
    <meta name="author" content="Syncfusion" />
    <link href="https://cdn.syncfusion.com/ej2/27.1.48/ej2-base/styles/material.css" rel="stylesheet" />
    <link href="https://cdn.syncfusion.com/ej2/27.1.48/ej2-buttons/styles/material.css" rel="stylesheet" />

    <link href="https://cdn.syncfusion.com/ej2/27.1.48/ej2-splitbuttons/styles/material.css" rel="stylesheet" />
    <link href="styles.css" rel="stylesheet" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    <script src="systemjs.config.js"></script>
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>

<body>
    <div id='loader'>LOADING....</div>
    <div id='container'>
        <div class='e-btn-group e-vertical'>
            <button class='e-btn'>HTML</button>
            <button class='e-btn'>CSS</button>
            <button class='e-btn'>Javascript</button>
        </div>
    </div>
</body>

</html>
#container {
    visibility: hidden;
}

#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}
.e-btn-group {
  margin: 25px 5px 20px 20px;
}

ButtonGroup does not support SplitButton component nesting in a vertical orientation.
