The <mat-select>, an Angular Directive, is used for <select> for enhance material design based styling..

In this chapter, we will showcase the configuration required to draw a select 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 {MatSelectModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatSelectModule,
      FormsModule,
      ReactiveFormsModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

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

import { Component } from '@angular/core';
import { FormControl } from "@angular/forms";
export interface Food {
  value: string;
  display: string;
}
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'materialApp'; 
   selectedValue: string; 
   foods: Food[] = [
      {value: 'steak', display: 'Steak'},
      {value: 'pizza', display: 'Pizza'},
      {value: 'tacos', display: 'Tacos'}
   ];
}

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

<form>
   <h4>mat-select</h4>
   <mat-form-field>
      <mat-select placeholder = "Favorite food" 
         [(ngModel)] = "selectedValue" name = "food">
         <mat-option *ngFor = "let food of foods" 
            [value] = "food.value">
            {{food.display}}
         </mat-option>
      </mat-select>
   </mat-form-field>
   <p> Selected food: {{selectedValue}} </p>
