Select list (cascading) modification

[Antoine]

Hello all, Is it possible to change a field type "Select list (cascading)" so that when the first list, you can only choose one option?

I just solve the problem without knowing why, I changed up the field within my screen, and the multi-selection is disabled automatically ...

I don't think I quite understand the question.  With a cascading select, you select one option in the first list and that  changes the available selection for the second list.  You only choose one option in the second list (which could be none) and all the possible combinations are unique, so you're only ever choosing a single option.  So I'm stuck on how "only choose one option" is different from what it already does?

On the screenshot there are two fields, one above can make several choices that will influence the choice possible in the field below. 

What I want is to choose only one option in the first field.

Is it clearer?

[Nic Brough -Adaptavist-]

No.  There is no selection on that first list, you choose one option, and the second box repopulates with the sub-list.  If you want only one option in the first list, change the option list so that there is only one.

This was apparently done automatically when I changed the place of field within the screen, but thank you for your answer!
