Adding a category as a button on the order screen

By default, categories appear on the right side of the screen in a column. Categories can also be added to the order screen as a menu button, if needed.

1. Type in the category name in the Menu Item Name field identically to the actual category name (you must already have the category created). Managers Menu > Menu Maintenance > Menu Items and Pricing
2. Choose the category that you want to see this button in
3. Choose Category as the department
4. 
5. Save
6. Alternatively, you can add an alias name for the category (in the image above, the category is labeled "< BACK". (This alias only applies to this menu button; it will not change your actual category name or reassign menu items within the category to this alias name!)

   2. Example:
7. Add the category name to a button on the Button Layout, save when completed.
