<Modifiers> are a group of items that pop up when another item is added.  eg say a customer requests a Gordons Gin, so your waiter adds it… Tilgo will then give a popup with the option to also add “Tonic”, “Coke” or “Grapefruit Juice”.

This gives the waiter quick access to the most likely choices and also allows you to upsell.

To set up modifiers, simply enter in the “Item”, “Modifier” and “Order” as per below.  “Order” will be the sequence in which the buttons are displayed on the popup, as per below.
