I have searched and tried everything that I googled to no avail... I have two question groups about Teachers, both have a ddl where the students can select a teacher. I want to exclude the selected teacher of the first ddl from displaying in the second ddl.
I would also consider doing some sort of validation that wouldn't allow the same teacher to be selected in both ddl.
There is no filtering, answer relevance or question validation for list (dropdown) questions, so the simplest solution would be to use multiple-choice questions with "Maximum answers" set to 1. Then you can use filtering and/or relevance and/or validation.
If that's not acceptable, you will need to use custom JavaScript to filter Q2 - the details of that script would depend on your survey set-up.
