Getting started in EJ2 JavaScript Button group control

10 Feb 20269 minutes to read

This section explains how to create a simple Button Group 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 dependencies are required to use the Button Group component in your application:

|-- @syncfusion/ej2-splitbuttons

Setup 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

Syncfusion® JavaScript controls come with built-in themes, which are available in the installed packages. It’s easy to adapt the Syncfusion® JavaScript controls to match the style of your application by referring to one of the built-in themes.

The quickstart application is preconfigured to use the Material theme 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-splitbuttons/styles/material.css';

You can check out the themes section to know more about built-in themes and CSS reference for individual controls.

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.

#loader {

  position: absolute;
  top: 45%;
  width: 30%;
}
.e-btn-group {
  margin: 25px 5px 20px 20px;
}

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">

<script src="https://cdn.syncfusion.com/ej2/32.2.3/dist/ej2.min.js" type="text/javascript"></script>
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>

<body>
    
    <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>


<script>
var ele = document.getElementById('container');
if(ele) {
  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>
</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.
