I ordered t his over-the-door ClosetMaid for my laundry room.  I needed storage space for the mops, brooms, duster, etc.  I chose to hang this using the over the door option and it works fine, but does not lay flat - I think if you secured it with the screws it would lay flatter.  Because it is behind the door and once all of the items are hung it does not really stick out too much.  It does what is intended.
