How to make Portfolio Project collection template with variable Image / Text number

Cyberdave, quick question. What you’re saying makes sense I think, but I’m unsure how to “add a switch for each field”. When I add a field to a collection in the back-end, I don’t see an option to associate a switch to a field. I of course see the option to add a switch, but I can’t figure out how it will define which text/image element is shown or not.

Screenshot of my Project Page collection for reference. Any help on what I’m doing wrong is greatly appreciated!
