basically, I have tags with children tags and on click on this parent tag I have to bind all it children to

on the other way, can onAdding observable allow Array of tags?

@Gbuomprisco if this is somthing already there please you help needed .

Much appreciated :)

my solution in case if anyone faced the same

[(ngModel)]="items"
then onAdding

this.items = [...this.items, ...tags];
reassign array did the job for me instead of pushing the updated array of tags

and for the observable onAdding you can return empty tag like so

 return of({
        value: null,
        display: null,
        readonly: true
      });

That's the correct approach
