Hi.
I'm trying to filter Items in a dropdown:
I want to show all the items where ID is not present in Hovedkategori-ID. In this case I don't want items with ID 1 and 2 to show.
How do I do this? I thought maybe this would work, but obviously not (i also tried with "=" instead for "in":
Filter(Kategori, Not(ThisItem.ID in 'Hovedkategori-ID')
