Multiple selection on a field through more subfield

[nboccassini]

I have these data (and other fields in this table):

Category	Name
L1	A
L1	B
L2	C
L2	D

I need to make two list box (one for L1 and one for L2) and I need the selections goes in OR mode.

Is it possible?

Thx

So L1 should only contain the two values A and B

and L2 should only contain the two values C and D?

[nboccassini]

Yes,

I try the expression in listbox

=if(Category='L1',Name)

I have a selection issue: when I select A from listbox L1, the selection are correctly applied on field Name, but when I select a value from L1 listbox (ex. A) and a value from L2 listbox (ex. B) the only selection applied on field Name is "B"

"Alternate States" could be a solution for you. But without knowing how you will use or apply the selections in you application it is a bit hard to give good advice.
