Example 1: Basic Material Select Dropdown

Here, we will create very simple example. first we need to import MatSelectModule for mat-select material design. so let's update app.module.ts, app.component.ts and app.component.html.

Let's follow step:

src/app/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/select';

@NgModule({

declarations: [

AppComponent

],

imports: [

BrowserModule,

BrowserAnimationsModule,

MatSelectModule,

],

providers: [],

bootstrap: [AppComponent]

})

export class AppModule { }

src/app/app.component.html

<h4>Angular Basic mat-select Example</h4>

<mat-form-field>

<mat-label>Select Website</mat-label>

<mat-select>

<mat-option *ngFor="let website of websites" [value]="website.value">

{{website.viewValue}}

</mat-option>

</mat-select>

</mat-form-field>

src/app/app.component.ts

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

interface Website {

value: string;

viewValue: string;

}

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']

})

export class AppComponent {

title = 'app-material3';

websites: Website[] = [

{value: '1', viewValue: 'HDTuto.com'},

{value: '2', viewValue: 'HDTuto.com'},

{value: '3', viewValue: 'Nicesnippets.com'}

];

}

Example 2: Material Select Dropdown with Reactive Form

Here, we will create very simple example using reactive form. first we need to import MatSelectModule, MatButtonModule, FormsModule and ReactiveFormsModule for mat-select material design. so let's update app.module.ts, app.component.ts and app.component.html.

Let's follow step:

src/app/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 { FormsModule, ReactiveFormsModule } from '@angular/forms';

import {MatSelectModule} from '@angular/material/select';

import {MatButtonModule} from '@angular/material/button';

@NgModule({

declarations: [

AppComponent

],

imports: [

BrowserModule,

BrowserAnimationsModule,

FormsModule,

ReactiveFormsModule,

MatSelectModule,

MatButtonModule

],

providers: [],

bootstrap: [AppComponent]

})

export class AppModule { }

src/app/app.component.html

<h1>Angular Material Select Box Example - HDTuto.com</h1>

<form [formGroup]="form" (ngSubmit)="submit()">

<mat-form-field>

<mat-label>Select Website</mat-label>

<mat-select formControlName="website">

<mat-option *ngFor="let website of websites" [value]="website.value">

{{website.viewValue}}

</mat-option>

</mat-select>

<mat-error *ngIf="form.get('website').hasError('required')">

Please select website

</mat-error>

</mat-form-field>

<button mat-raised-button color="accent">Submit</button>

</form>

src/app/app.component.ts

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

import { FormBuilder, FormGroup, Validators} from '@angular/forms';

interface Website {

value: string;

viewValue: string;

}

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']

})

export class AppComponent {

title = 'app-material2';

websites: Website[] = [

{value: '1', viewValue: 'HDTuto.com'},

{value: '2', viewValue: 'HDTuto.com'},

{value: '3', viewValue: 'Nicesnippets.com'}

];

form: FormGroup = new FormGroup({});

constructor(private fb: FormBuilder) {

this.form = fb.group({

website: ['', [Validators.required]],

})

}

get f(){

return this.form.controls;

}

submit(){

console.log(this.form.value);

}

}

You can easily run by following command:

ng serve
