Can you pull that book out of the bookshelf but not all the way. I want it to be on the shelf so I can shoot the cover with the other books in the background.

Is the description understandable?

'Dangling' to me suggests at least the possibility of some movement. I'd say 'hanging off the dresser'.
Thank you, Clive.

That doesn't sound very natural to me.

I dangled the ribbon in front of the cat.

I dangled my car keys to indicate that I was ready to leave.

Dangling implies movement to me, and only a tiny portion is still "attached." If you think of the Spiderman movies, usually there is more than one person in the course of the movie who will be dangling from a ledge, gripping desperately with their fingertips, so Spidey can come rescue them.

If you tell me a book is dangling in the air, it almost sounds like a ghost is there.
Thanks, GG.
