Any of those help I solved it! I forgot to add formArrayName="habitaciones" in the parent div of the *ngFor directive where I iterate the formArray. That's why it didn't recognize the formArray and somehow the *ngFor's index was not loaded. My bad, but maybe this helps somebody.

may help you . I'm currently working on an angular app with an array of items (objects). I want to display each object in the array in its own list item, but want to limit the height of the list to 9 rows, before it starts on a new list next to it. So if the array has 13 elements, array[0] to array [8] should be listed in the first list, in the first column, while array [9] to array [12] should be listed in a new list. How can I make *ngFor stop looping at index = 9, and start looping from there on another list? , One way of doing this is using Array.prototype.slice method:

With these it helps if you are using angular 2+ then you should do like this for getting index , so in angular 2 onwards you don't have ng-repeat it replaced by *ngFor
code :
<li *ngFor="let user of userObservable | async as users; 
                         index as i; ">
   {{i}}/{{users.length}}. {{user}}
</li>
<li *ngFor="let user of userObservable | async as users; 
                         let i = index; ">
   {{i}}/{{users.length}}. {{user}}
</li>
