how can i make that??

Don’t, use a Skeleton Screen:

Html file:

<ion-content *ngIf="pageLoaded">
 <!-- all your stuff -->

ts file:

  selector: 'page-home',
  templateUrl: 'home.html',
export class HomePage {
    pageLoaded:boolean = false;

    constructor() {

   loadData() {
       ... all your code
       this.pageLoaded = true;
