Filter logic for multiple choice questions using cases as choices

Users

In a current form, I have two multiple choice questions (checkbox lookup
tables) that have cases as choices. I want the second question to only
display the case choices that were not selected in the first question. Is
it possible to do this using the Logic in the second question?

Thank you!

I could be wrong but I don't think that's possible though maybe something
like this would work (but would likely require some custom expressions):

  • full_case_list = "case1 case2 case3"
  • cases_selected = "case1 case2"
  • regex = replace(cases_selected, ' ', '|') # replace spaces with '|'
    to create regex OR
  • filtered_list = replace(full_case_list, regex, '')

Use "filtered_list" as the source for the datasource.
