Angular Material 7 - CheckBox

The <mat-checkbox>, an Angular Directive, is used as a enhanced checkbox with material design stypng and animation capabipties.

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

Create Angular Apppcation

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

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 {MatCheckboxModule} from  @angular/material ;
import {FormsModule, ReactiveFormsModule} from  @angular/forms ;
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatCheckboxModule,
      FormsModule,
      ReactiveFormsModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

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

<h2 class = "tp-h2">Checkbox configuration</h2>
<section class = "tp-section">
   <mat-checkbox class = "tp-margin" [(ngModel)] = "checked">Checked</mat-checkbox>
   <mat-checkbox class = "tp-margin" [(ngModel)] = "indeterminate">Indeterminate</mat-checkbox>
</section> 
<section class = "tp-section">
   <mat-checkbox class = "tp-margin" [(ngModel)] = "disabled">Disabled</mat-checkbox>
</section>
<h2 class = "tp-h2">Result</h2>
<section class = "tp-section">
   <mat-checkbox
      class = "tp-margin"
      [(ngModel)] = "checked"
      [(indeterminate)] = "indeterminate"
      [labelPosition] = "labelPosition"
      [disabled] = "disabled">
      Sample Checkbox
   </mat-checkbox>
</section&gt

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

.tp-h2 {
   margin: 10px;
}
.tp-section {
   display: flex;
   apgn-content: center;
   apgn-items: center;
   height: 60px;
}
.tp-margin {
   margin: 0 10px;
}

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

import { Component } from  @angular/core ;
import { FormControl } from "@angular/forms";
@Component({
   selector:  app-root ,
   templateUrl:  ./app.component.html ,
   styleUrls: [ ./app.component.css ]
})
export class AppComponent {
   title =  materialApp ;
   checked = false;
   indeterminate = false;
   labelPosition =  after ;
   disabled = false;
}
