My QC solution has 9 buttons most of which need a required response in which user chooses from a dropdown populated by a coded value domain:

This works! Great!
But when a user unwillingly touches a button they get this dropdown and are obliged to enter something.
I would like to know how to back down from this, after I touched the wrong button, without submitting a record or without closing the app altogether.
Is is possible to 'unclick' the dropdown?
Thanks in advance for your time.
