EDIT: I resolved this myself by adding a View that was filtered to just mime type: application/pdf, then tied that to an Entity Browser. A Content type field was then configured to use that Entity Browser. Voila!

Greetings! I'm quite new to Drupal and stumbled upon something that I assume is achievable, I just can't figure out how to do it. I have a content type named Employee Profile. Inside, I have an entity reference field named Biography. Even though I have the Bundles > Document reference type checked, I still see the images and other non-documents in my entity browser.

I would love to limit this to just documents, or better yet, just PDF files. The idea is that each Employee Profile will have some text about the employee, a photo, etc... and a PDF version of their bio.

Any ideas?

Thanks!
