Menu Items can be sorted generally by category. For example, all of the drinks could print on the top of the check and desserts can print at the bottom. However, if you need to further define how menu items appear in the kitchen/virtual check, you may set priority levels.
Priority Sort Levels must be set on ALL menu items if it is used for one. Otherwise, it will randomly group and will not know the order for the other priority levels.
It is easiest to prioritize by groups. For example, Drinks could be from 1-1000, giving an ample range to add more drink menu items as the menu grows. 1000=top of receipt. 5000=middle, 9000=bottom.
