Hi, I have a question about how to set non-substantive response options like ‘don’t know’ or ‘unknown’ in a “select all that apply” multiple choice question, is there a way to make these response “exclusive” so if ‘don’t know’ or ‘unknown’ is selected, none of the other options in the list would be selected?
For example:
What are your favorite color(s)? Select all that apply.
Red
Blue
Orange
Don’t Know
If Blue and Red are selected, Don’t Know can never be selected.
Suggestions?
