Collections On Submenu

Hey everyone!

Quick question: can you put collections in a submenu? I’m not seeing anyway to do this and I’m wondering if I missed something or if it may not be possible.

I’d like to have my “Case Studies” in my menu, then give viewers the ability to click on that to go to the collections page to see all my case studies, or click on one of the options from a submenu dropdown that also displays all my case studies.

I’ve already built my case studies in a collection, but I’m pretty new to collections so I’m not sure if I can put a setting somewhere to add new submenus when I add new collections, or if I need to link them manually.

Thanks!
