I have thought about this issue and tried to visualise it the best I can for myself but I can't figure it out. Apologies if the answer is very simple, I just can't get there myself!
I am aware that you can set a View to query multiple different CPTs and then design the output within the Loop Editor. I wish to be able to do this but to use a different Content Template for each returned result, dependant on the CPT. Is this possible and how would I achieve this?
For example; for every result that is CPT of "Author" I would like to use an "Author" Content Template designed just for this CPT and for every result that is CPT of "Book" then I would like to use a "Book" Content Template.
I hope this makes sense. Let me know if there is anything else you need.
