I have two documents in my Firebase DB:
in the first I have the customer cards;
in the second I created customer groups
From these screens you can get an idea of the structure:
in my app I want to be able to select each group and view the list of all customers contained in that group.
SLICE(SELECT(data.schedeDellaScienzaForGuest, CONTAINS(item.id, pageVars.percorsiSelectedPageVar.schede ) ), 0 ,100)
helps me select the group, but then shows me only the 0 (zero) element of the array ( schede ). How can I create a cycle to see them all?
I hope I have explained
