This is very conveniently solved in Survey123. Waiting for implementing something similar to Collector too!
I agree that this would be a great addition to the collector apps functionality. Our users are currently scrolling through multiple fields to collect the correct data. With a smart form solution this could be solved by assigning specific fields to show through the selection of another field.
Smarter data collection forms are on the 'Planned' feature improvements coming to Collector app in the future. See the Sneak Peek section, Sneak peek—Collector for ArcGIS | ArcGIS.
