[How do you disable a resourcepack on your server?]

I recently downloaded Chat Enhancer, a minehut market product, and didn't like it, so I removed it. But their resourcepack is still locked in the server, is there any way to remove this?

[Making an item unable to be moved or dropped]

Greetings,

I scouted the forums in search of a way to have an item in your inventory that makes so you are unable to change position or drop the item. This item will also execute a command like the script below.

 

options:
	item: stick named "&fClick to open Menu"
	command: /menu

on first join:
	give player {@item}

on right click:
	execute console command "{@command}" if player's tool is {@item}

 

So the question here is, is there a way to make a feature that makes you unable to drop and move this item?
