Installing Syncfusion ButtonGroup package

To install ButtonGroup package, use the following command.

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

The above package installs Button dependencies which are required to render the ButtonGroup component in the Angular environment.

Adding Button module

Import Button module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-buttons.

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

// Imported Syncfusion button module from buttons package.
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';

import { AppComponent }  from './app.component';

@NgModule({
 imports:      [ BrowserModule, ButtonModule ], // Registering EJ2 Button Module
 declarations: [ AppComponent ],
 bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding Syncfusion ButtonGroup component

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

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

@Component({
 selector: 'app-root',
 template: `<div class='e-btn-group'>
             <button ejs-button>HTML</button>
             <button ejs-button>CSS</button>
             <button ejs-button>Javascript</button>
           </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.

@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

import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

/**

 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Vertical Orientation

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