In this chapter, we will showcase the configuration required to use a mat-form-field control in 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 {MatInputModule,MatOptionModule, MatSelectModule, MatIconModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
   declarations: [
   imports: [
      MatInputModule,MatOptionModule, MatSelectModule, MatIconModule,
   providers: [],
   bootstrap: [AppComponent]
export class AppModule { }

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

.tp-container {
   display: flex;
   flex-direction: column;
.tp-container > * {
   width: 100%;

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

<div class = "tp-container">
   <mat-form-field appearance = "standard">
      <input matInput placeholder = "Input">
      <mat-icon matSuffix>sentiment_very_satisfied</mat-icon>
      <mat-hint>Sample Hint</mat-hint>
   <mat-form-field appearance = "fill">
      <textarea matInput placeholder = "Textarea"></textarea>
   <mat-form-field appearance = "outline">
      <mat-select placeholder = "Select">
         <mat-option value = "A">A</mat-option>
         <mat-option value = "B">B</mat-option>
         <mat-option value = "C">C</mat-option>      


Verify the result.
