Conveying view layer logic in Questionnaire resource

1

I’m imaging some declarative means of describing things like if answer option x is selected for question 3, then show the previously hidden questions 4-5. My search so far hasn’t turned up anything like this. Will future FHIR standards describe something like this? Until then, are there common strategies or de facto “standards” handling this?

Have you looked at Questionnaire.item.enableWhen?

Thank you Lloyd! I had seen that but it didn’t immediately register since I was thinking in terms of HTML where enabled has a specific meaning.
