I have another problem with this setup described above, I can’t figure out how to disable the plus and minus buttons and the Change Price buttons in the payment screen for the Kitchen department.
If users click on the plus or minus button, this system doesn’t work (changed amount doesn’t get updated in the inventory of the new half-product). Therefore I want to either disable them or at least have a way to intercept the click through an event/rule. I haven’t found any way to do this though.
Any suggestions?
