Can't move certain files in Google Drive

Question

I'm a student, and currently trying to organize all of my documents and slideshows into folders for easy access.
Although, some of these documents and slides I cant move, the option is just greyed out.

It might be worth noting that these documents and slides have been submitted into classroom, but I don't think this is the sole reason, as I can still move other documents that I have submitted to various folders.
Is there a way to still move these documents? All it does is create a shortcut, which isn't what I want as I'm trying to clean everything up.

You mention

...these documents and slides have been submitted into classroom...

You cannot move your documents any more because you do not have editing rights any more. You just have viewing rights.
You will also notice that you can neither delete these files.

That is default behaviour in classroom which is controlled by your teacher/professor so that -for example- submitted work cannot be altered by students (especially when there is a deadline).

To answer your question, "Is there a way to still move these documents?", no you cannot.
