I´m developing an app using appsheet.
In the app, i would scan a QR (secret number) and compare it with a table list (all secret numbers).
If the number matchs it supposed to allow the registration, if dont it supposed to not allow.
I´m using valid_if expression to compare the scanned number with the all secret number list.
However, it show a dropdown with all secret numbers.
How yo hide this dropdown from show all secret numbers?
