This section explains how to create a simple CSS ButtonGroup, and demonstrate the basic usage of the CSS ButtonGroup component in an Angular environment.

Dependencies

The following list of dependencies are required to use the ButtonGroup component in your application.

|-- @syncfusion/ej2-splitbuttons

Setup Angular environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion® ButtonGroup package

Syncfusion® packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion® package from npm link.

Currently, Syncfusion® provides two types of package structures for Angular components,

  1. Ivy library distribution package format
  2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion® Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-buttons package to the application.

npm install @syncfusion/ej2-angular-buttons --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion® Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-buttons@ngcc package to the application.

npm install @syncfusion/ej2-angular-buttons@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-buttons:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding Syncfusion® ButtonGroup component

Modify the template in app.component.ts file to render the ButtonGroup Component.

import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { Component } from '@angular/core';

@Component({
imports: [
        
        ButtonModule
    ],
    standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render ButtonGroup. -->
                  <div class='e-btn-group'>
                    <button ejs-button>HTML</button>
                    <button ejs-button>CSS</button>
                    <button ejs-button>Javascript</button>
                  </div>
                </div>`
})

export class AppComponent { }

To render Button in CSS ButtonGroup component, import Button module into the angular application(app.module.ts) from the package @syncfusion/ej2-angular-buttons and its styles in style.css.

Adding CSS reference

Add ButtonGroup component’s styles as given below in style.css.

@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';

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a basic ButtonGroup component.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';

@Component({
imports: [
        
        ButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render ButtonGroup. -->
                  <div class='e-btn-group'>
                    <button ejs-button>HTML</button>
                    <button ejs-button>CSS</button>
                    <button ejs-button>Javascript</button>
                  </div>
                </div>`
})

export class AppComponent { }
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Orientation

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

Vertical Orientation

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

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

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';

@Component({
imports: [
        
        ButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render ButtonGroup. -->
                <div class='e-btn-group e-vertical'>
                    <button ejs-button>HTML</button>
                    <button ejs-button>CSS</button>
                    <button ejs-button>Javascript</button>
                </div>
              </div>`
})

export class AppComponent { }
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

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