Is there way to restrict answers within a checkbox question. For example, if there are 4 choices (a – d) then making it where they can only select either a and/or b and c and/or d?
There is the ability to impose some “Answer Requirements” under the “Validation” tab when you edit a question. You can limit the number of checks or requirement a certain number of checks.
If this doesn’t suit your needs, maybe try a Radio Button and just list out the combinations available to survey takers.
