Angular Material 7 - Toggle Button

The <mat-button-toggle>, an Angular Directive, is used to create a toggle or on/off button with material styling and animations. mat-button-toggle buttons can be configured to behave as radio buttons or checkboxes. Typically they are part of <mat-button-toggle-group>.

In this chapter, we will showcase the configuration required to draw a button toggle control using Angular Material.

Create Angular Application

Follow the following steps to update the Angular application we created in Angular 6 - Project Setup chapter −

Step Description
1 Create a project with a name materialApp as explained in the Angular 6 - Project Setup chapter.
2 Modify app.module.ts, app.component.ts, app.component.css and app.component.html as explained below. Keep rest of the files unchanged.
3 Compile and run the application to verify the result of the implemented logic.

Following is the content of the modified module descriptor app.module.ts.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {MatButtonToggleModule, MatIconModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
   declarations: [
   imports: [
      MatButtonToggleModule, MatIconModule,
   providers: [],
   bootstrap: [AppComponent]
export class AppModule { }

Following is the content of the modified CSS file app.component.css.

.tp-selected-value {
   margin: 15px 0;

Following is the content of the modified HTML host file app.component.html.

<mat-button-toggle-group #group = "matButtonToggleGroup">
   <mat-button-toggle value = "left">
   <mat-button-toggle value = "center">
   <mat-button-toggle value = "right">
   <mat-button-toggle value = "justify" disabled>
<div class = "tp-selected-value">Selected value: {{group.value}}</div>


Verify the result.
