item undroppable system request

I searched and found nothing on this.

I'm using Weaaddar's Drag and Drop system.
I have certain items in my map I want to make undroppable but still make it so you can move them to whenin the inventory, but not drop it onto another hero.

If possible I would like to be able to add a single item not item type to the list of undroppable items, ingame (some items can't be dropped after used). But prefine certain item types as undroppable (some items can't be dropped at all)

A little about how inventory works in my map:
The main inventory page(outside of bags), is where each bag is kept(max is 5)
Even if you have say 1-4 bags all items are sent straight into a bag.


Basicly, what i'm asking for is a system for Weaaddar's Drag and Drop system
that makes certain item-types undroppable and certain items undroppable after item is used.

Note: I will give full credit for this in my map in my Credits section and give rep.
