Management > Products > Menu List > Menu
Select a Menu Category, Click Edit Product Properties
For any Item you wish to have modifiers (portions and order tags) displayed automatically, check the box for Auto Select.
Sub Menus are not Modifiers (Order Tags). Modifiers (i.e. sauce, cheese type etc) are called Order Tags in SambaPOS, and they are located here:
Management > Tickets > Order Tags
Create your modifiers there, then choose the mappings. Map Order Tags to Product Groups or individual Products.
You’ll eventually get the hang of it. Play with it more. SambaPOS is wonderfully programmed and is extremely flexible and powerful.
