Hello! Looking for help in identifying what hardware I need to reattach the middle door on my wardrobe. The top of the door has completely fallen off, while the bottom of the door remains connected through (1) a sliding hinge and (2) a plastic looking plug which connects the corner of the door to the frame such that it can pivot. I do not know how the top of the door was previously connected, and cannot seem to find any parts that have off, although they may be hidden amongst my clothes. I assume there must have been some kind of plastic piece connecting the door to the frame to allow it to pivot. I would be very grateful if anyone can help identify what I need to fix this!
