Items can be forced into a players inventory like a menu. eg. you can make an item stay in the inventory for a server selector, or kit selector. In the 'open-with-item' just add 'stationary: [hotbar number 0-8]' inside it, and the item will be an unmovable menu in the hotbar location chosen from 0-8. To allow to move the item around, simply use commandpanel.move.[panel perm]
