You can set minimum and maximum requirements for modifier groups. For example, the modifier group 'Sauces' might have a maximum of 1 and a minimum of 0. That would mean that on the kiosk, customers are not required to make a selection but can only choose up to one option.
To set minimum and maximum requirements:
- Log in to the GRUBBRR Portal
- Select 'Menu' from the left sidebar
- Select 'Modifier Groups' from the dropdown
- Find the modifier group you wish to add a minimum and/or maximum requirement for
- Enter a numerical value into the Min or Max columns
- Select the green checkmark to the right of the text box
- Sync your changes to the kiosk
