Please consider the following scenario for Survey 123 Cascading Selects.
Category with 2 options A, B
Group with 4 options 1, 2, 3, 4
If the user selects A for question 1 then the valid options are 1, 2, 3 for Question 2
If the user selects B for question 1 then the valid options are 2, 3, 4 for Question 2
I know this can be done with cascading selects but the "entries" for 2 and 3 have to be duplicated like this
It would be nice if this could be achieved without having to duplicate the options for the group question? i.e. Normalised. Is this possible?
How do we allow the options for the group to be allowed in 2 (or more) categories?
Thanks for the problem description. The main issue is that at this time, the choice_filter currently doesn't support functions, which would be able to accomplish this. I've added this comment to the enhancement request to address that.
Take a look at or_other and choice_filter and https://community.esri.com/thread/208453-xlsform-issue - both of these show how a choice_filter can support a value that can be filtered by more than one previous choice.
