Hello to all, welcome to therichpost.com. In this post, I will tell you, Angular 16 Step form working demo with validation.

Guys with this we will cover below things:

1. Angular 16 Reactive Form Implelemtnation.
2. Reactive forms validation email with valid format.
3. Angular custom stepper
4. Angular16 Reactive Form Responsiveness with Bootstrap 5.

Angular16 came and if you are new then you must check below link:

1. Angular 16 Tutorials

Here is the code snippet and please use carefully:

1. Very first guys, here are common basics steps to add angular 16 application on your machine and also we must have latest nodejs version installed for angular 16:

$ npm install -g @angular/cli

$ ng new angularform // Set Angular 16 Application on your pc

cd angularform // Go inside project folder

2. Now run below commands to set bootstrap 5 modules into our angular 16 application for responsiveness (optional):

npm install bootstrap

npm i @popperjs/core

3. Now friends we just need to add below code into angularform/angular.json file (optional):

"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
          ],
"scripts": [
              ...
               "node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"
           ]

4. Now guys we will add below code into our angularform/src/app/app.module.ts file:

...
import { FormsModule } from '@angular/forms';
import { ReactiveFormsModule } from '@angular/forms';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
  ...
    ReactiveFormsModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

5. Now guys we will add below code into our angularform/src/app/app.component.ts file:

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular13bestcode';
 

    personalDetails:any = FormGroup;
    addressDetails:any= FormGroup;
    educationalDetails:any= FormGroup;
    personal_step = false;
    address_step = false;
    education_step = false;
    step = 1;
  
    constructor(private formBuilder: FormBuilder) { }
  
    ngOnInit() {
  
          this.personalDetails = this.formBuilder.group({
              name: ['', Validators.required],
              email: ['', Validators.required],
              phone: ['',Validators.required]
          });
  
          this.addressDetails = this.formBuilder.group({
              city: ['', Validators.required],
              address: ['', Validators.required],
              pincode: ['',Validators.required]
          });
  
          this.educationalDetails = this.formBuilder.group({
              highest_qualification: ['', Validators.required],
              university: ['', Validators.required],
              total_marks: ['',Validators.required]
          });
    }
  
    get personal() { return this.personalDetails.controls; }
    
    get address() { return this.addressDetails.controls; }
  
    get education() { return this.educationalDetails.controls; }

    next(){
 
      if(this.step==1){
            this.personal_step = true;
            if (this.personalDetails.invalid) { return  }
            this.step++
      }
  
      else if(this.step==2){
          this.address_step = true;
          if (this.addressDetails.invalid) { return }
              this.step++;
      }

      
  
    }
  
    previous(){
      this.step--
     
      if(this.step==1){
        this.address_step = false;
      }
      if(this.step==2){
        this.education_step = false;
      }
     
    }
  
    submit(){
      
      if(this.step==3){
        this.education_step = true;
        if (this.educationalDetails.invalid) { return }
        alert("Well done!!")
      }
    }
}

6. Finally we will add below code into our angularform/src/app/app.component.html file:

<div class="container py-5">
  
  <div class="row"> 
    <div class="col-md-12 col-md-offset-3">
        <form [formGroup]="personalDetails" id="msform">

            <ul id="progressbar">

                <li [ngClass]="step>=2 ? 'active' : 'inactive'">Social Profiles</li>
                <li [ngClass]="step==3 ? 'active' : 'inactive'">Account Setup</li>
            </ul>
            <!-- fieldsets -->

            <fieldset  *ngIf="step == 1" >
                <h2 class="fs-title">Personal Details</h2>

            </fieldset>
        </form>
         <form [formGroup]="educationalDetails" id="msform">
