Angular13 came and if you are new then you must check below link:

  1. Angular 13 Tutorials

Here is the code snippet and please use carefully:

1. Very first guys, here are common basics steps to add angular 13 application on your machine and also we must have latest nodejs version(14.17.0) installed for angular 13:

$ npm install -g @angular/cli

$ ng new angularform // Set Angular 11 Application on your pc

cd angularform // Go inside project folder

2. Now run below commands to set bootstrap 5 modules into our angular 13 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.min.js"
           ]

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

...
import { ReactiveFormsModule } from '@angular/forms';

@NgModule({
...
  imports: [
   ...
    ReactiveFormsModule,
   
  ],
  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!: FormGroup;
    addressDetails!: FormGroup;
    educationalDetails!: 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>=1 ? 'active ' : 'inactive'">Personal Details</li>
                <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>
                <input type="text" formControlName="name"  [ngClass]="{ 'is-invalid': personal_step && personal.name.errors }" placeholder="Full Name"/>

                <input  (click)="next()" type="button" name="next" class="next action-button" value="Next"/>
            </fieldset>
        </form>
         <form [formGroup]="educationalDetails" id="msform">
            <fieldset *ngIf="step == 3">
