Step3: 

Now we start the designig part of multilevel form, open the file where you want to integrate the code, here i am open register.ts file

import {NavController, NavParams, ToastController, Platform, Events} from 'ionic-angular';

}
 
save(slideOneForm, slideTwoForm, slideThreeForm) {

 if (this.fatchdata['status'] == 200) {

 let alert = this.alertCtrl.create({
