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: [

BrowserAnimationsModule,

FormsModule,

ReactiveFormsModule,

MatButtonModule

],

providers: [],

</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: 'ItSolutionStuff.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);
