FAQ

Everyone can see everyone's menus...

Holographic Displays requires ProtocolLib to make buttons visible per player. Also note that PUBLIC menus are by design visible and usable by every player. That is sothat you can open them permanently at a set location with /m op [menu name].

Users can only see buttons if they are OP!

This is most likely caused by an erroneous setup. If you copy / pasted the wiki example one by one, you might have missed removing or changing the per button permission node. This of course causes the users who do not have this node not to see the buttons.

        # The permission a player needs to see the button.
        permission: menu.click

My public menu doesn't follow players even though I set followingOnMove to true!

Public menus aren't attributable to players and therefore don't follow anyone.
