I’m setting up cascading select questions for regions, provinces and municipalities/cities in the Philippines. The problem is that the National Capital Region has no provinces. Only cities. How do I go about setting up the cascading select question?
Another option would be to filter the following steps of the cascade by a relevant clause to exclude the Capital region case. I.e. only if ${VariableNameRegion} != “ChoiceNameOfCapitalRegion” and ${VariableNameRegion} != ‘’), the Province and Municipality parts would be active.
The result would be that these variables would be empty in the dataset for the Capital region case. If you don’t want this you might need to follow an approach like hakan_cetinkaya described.
