Angular Material 7 - Radio Button


The <mat-radiobutton>, an Angular Directive, is used for <input type="radio"> for enhance material design based styling..

In this chapter, we will showcase the configuration required to draw a radio button 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 {MatRadioModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
   declarations: [
   imports: [
   providers: [],
   bootstrap: [AppComponent]
export class AppModule { }

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

.tp-radio-group {
   display: inline-flex;
   flex-direction: column;
.tp-radio-button {
   margin: 5px;
.tp-selected-value {
   margin: 15px 0;

Following is the content of the modified ts file app.component.ts.

import { Component } from '@angular/core';
import { FormControl } from "@angular/forms";
import { Validators } from "@angular/forms";
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
export class AppComponent {
   title = 'materialApp'; 
   favoriteSeason: string;
   seasons: string[] = ['Winter', 'Spring', 'Summer', 'Autumn'];

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

<mat-radio-group class = "tp-radio-group" [(ngModel)] = "favoriteSeason">
   <mat-radio-button class = "tp-radio-button"
      *ngFor = "let season of seasons" [value] = "season">
<div class = "tp-selected-value">
   Selected Season: {{favoriteSeason}}


Verify the result.

Radio button


  • As first, we've created an radio button group using mat-radio-group bound with ngModel.

  • Then, we've added radio buttons using mat-radio-button.
