Getting started in EJ2 JavaScript Button group control

29 Jul 20267 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 seed repository is pre-configured with the Essential® JS 2 package.

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.

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 --save

The 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.

    <div>
        <!--element which is going to render-->
        <div class='e-btn-group'>
            <button class='e-btn'>HTML</button>
            <button class='e-btn'>CSS</button>
            <button class='e-btn'>Javascript</button>
        </div>
    </div>

</body>

</html>

Run the application

Now, run the application in the browser using the following command.

npm run start

The following example shows a basic ButtonGroup component.

<!DOCTYPE html><html lang="en"><head>
    <title>EJ2 Button-Group</title>
    <meta charset="utf-8">

</head>

<body>
    
    <div id="container">
        <div class="e-btn-group">
            <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>

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/ej2/34.1.29/ej2-base/styles/material.css" rel="stylesheet">
    <link href="https://cdn.syncfusion.com/ej2/34.1.29/ej2-buttons/styles/material.css" rel="stylesheet">
    <link href="https://cdn.syncfusion.com/ej2/34.1.29/ej2-popups/styles/material.css" rel="stylesheet">
    <link href="https://cdn.syncfusion.com/ej2/34.1.29/ej2-splitbuttons/styles/material.css" rel="stylesheet">
    <link href="styles.css" rel="stylesheet">
    
    
<script src="https://cdn.syncfusion.com/ej2/34.1.29/dist/ej2.min.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>

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