Best to use search in future..But ill tell you this time.
Create a [DEV] char, then go ingame and type in /DEV openconsole
Once you done that press CTRL + Shift together.
In the console type in dropitem_custom "Item Index" "Amout of slots" "Option Index"
Item index is in data/share/item then find itemetc
Option index is in data/share/item then find itemoption
