Hello to all, welcome to therichpost.com. In this post, I will tell you, Angular 7 Step form Working Example.

If you are new in Angular 7 then you can check my old posts related to Angular 7.

In this post, I am using Angular latest version Angular 7.2.4 and Angular Material.

Here is the working code snippets you need to follow carefully:

---

1. Here is the basics npm commands you need to run to install latest angular setup and angular material:

ng new angularStepper

cd angularStepper

npm install --save @angular/material @angular/cdk @angular/animations

ng serve

 

2. Here is the code,  you need to add into app.module.ts file:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { MatStepperModule } from '@angular/material/stepper';
import { AppComponent } from './app.component';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { MatFormFieldModule } from '@angular/material';
import { MatInputModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatButtonModule } from '@angular/material/button';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MatStepperModule,
    FormsModule,
    ReactiveFormsModule,
    MatFormFieldModule,
    MatInputModule,
    BrowserAnimationsModule,
    MatButtonModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

 

3. Here is the code you need to add into your styles.css file:

/* You can add global styles to this file, and also import other style files */
@import '~@angular/material/prebuilt-themes/deeppurple-amber.css';

 

4. Here is the code you need to add into your app.component.ts file:

import { Component } from '@angular/core';
import {FormBuilder, FormGroup, Validators} from '@angular/forms';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angularphp';
  firstFormGroup: FormGroup;
  secondFormGroup: FormGroup;
  isOptional = false;

  constructor(private _formBuilder: FormBuilder) {}

  ngOnInit() {
    this.firstFormGroup = this._formBuilder.group({
      firstCtrl: ['', Validators.required]
    });
    this.secondFormGroup = this._formBuilder.group({
      secondCtrl: ''
    });
  }
}

 

5. Here is the code, you need to add into your app.component.html file:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons"rel="stylesheet">
<button mat-raised-button (click)="isOptional = !isOptional">
  {{!isOptional ? 'Enable optional steps' : 'Disable optional steps'}}
</button>
<mat-horizontal-stepper linear #stepper>
  <mat-step [stepControl]="firstFormGroup">
    <form [formGroup]="firstFormGroup">
      <ng-template matStepLabel>Fill out your name</ng-template>
      <mat-form-field>
        <input matInput placeholder="Last name, First name" formControlName="firstCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step [stepControl]="secondFormGroup" [optional]="isOptional">
    <form [formGroup]="secondFormGroup">
      <ng-template matStepLabel>Fill out your address</ng-template>
      <mat-form-field>
        <input matInput placeholder="Address" formControlName="secondCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperPrevious>Back</button>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step>
    <ng-template matStepLabel>Done</ng-template>
    You are now done.
    <div>
      <button mat-button matStepperPrevious>Back</button>
      <button mat-button (click)="stepper.reset()">Reset</button>
    </div>
  </mat-step>
</mat-horizontal-stepper>
