Ok here is an update on my flow… several things to note…
-
The change Drink button and Change Side buttons only show up if their order type is selected. Example Change Side button only shows up if a side is selected and Change Drink button only shows if a Drink is selected.
-
This setup lets you swap out designated menu items in the combo and lets you change portions and adjusts price accordingly.
-
The prices are all promotion prices so a large Diet Coke that is part of a combo costs less than a Large Diet Coke that is not part of a combo.
Anyway I am 95% done… few formatting things to iron out like the actual header name… Combo 1 is a place holder also I want to tweak some of the looks of portions on screen etc.
I am not quite ready to share the configuration yet but I will soon hopefully.
EDIT: Forgot to mention also if you are in middle of a change of an item it will not let you select anything other than the type of item you are swapping… it will warn you. Here is an example of that:
