I have been asked to develop a pdf where we'd have people use a dropdown menu to rank five topic areas 1,2,3,4, or 5. If they select a 2 for the dropdown of the first topic area, I want the "2" to be removed from the other dropdowns (leaving just 1,3,4,5 for the remaining drop downs), and so on for each number selected in the dropdowns, so they can only use any number once. I know how to do this in excel, but I'm being asked to do this in a PDF. I was just curious if this is even possible in a pdf???? If not via dropdown, then maybe radio buttons?
