superlockslot
by arch-mc
superlockslot lets players lock selected inventory slots so that stray drop presses cannot discard their items.
What it does
Locked slots refuse drops: pressing the drop key over a locked slot, including a hovered item in the open inventory, leaves the stack in place. The lock is set per slot, so the rest of the inventory and hotbar keep normal dropping. The mod targets accidental item loss rather than adding new gameplay.
The client needs the mod, and the server may run without it, since the protection works on the player's side. Fabric API, Cloth Config API and Mod Menu are required, and the mod is a Fabric build for 1.20.1 and 1.21.11, released under All rights reserved (not open source).
Key features
Accident-proof slots
Selected slots block item drops, which guards valuable stacks in the hotbar or main inventory.
Lock with a key
A dedicated key toggles the lock on the selected slot, so no menu visit is needed.
Inventory drop protection
Drop presses aimed at a hovered item in an open inventory are blocked for locked slots.

What the author says
Locks selected slots, so you can't drop items from them using Q (or another key). To drop something open your inventory and drop it using Q when hover an item.
