Answer 1

So you want to get an array from your .ts file to your html dynamically and load the content into the ion-items? Set a global variable into your .ts file. Lets call it data.

Then your html should look like this: home.html:

<ion-list *ngFor="let data-object of data">
    <ion-item>
      <ion-label position="floating">{{data-object.value}}</ion-label>
      <ion-checkbox color="secondary" value="{{data-object.value}}"></ion-checkbox>
    </ion-item>
</ion-list>

Where data is your array with data objects.
