Displaying custom items in the crafting grid.

I had an awesome idea today, but I have no idea how to implement it. Could someone guide me on this?

When a player opens their inventory, they will be shown a display like this:


These items will not be move-able or interact-able and will not drop when exiting the inventory. My custom server does not use crafting, so that is not a problem for me. Does anyone have any idea how to go about doing this? Thanks!

 

The only thing i think on how this will work is that you give all the items you want not to move a lore or display name, Such as SoulBound. This will make it so you can check for that Display name. So you can get a inventory click event and if the item has that display name you can make it so it cancels the event and makes that item go back.
