Category Groups are used to organize or segregate categories. You might want to create a category with several sub-categories. For example, you have Meals and Snacks categories. Without grouping these categories, it will make the category display on your register screen longer. We can group these categories into Food so that your category list is much shorter and easier to navigate.
You can add category groups in the Back Office.
In the Back Office, under Listings, navigate to the Categories section.
Click on the Category Group tab, then click New Category Group.
Input the name of your Category Group. Click Save.
To assign Categories under your Category Group, click on the Category tab.
Click the edit icon of the Category you want to assign a Category Group.
On the Edit Category pop-up, navigate to Category Group and select the category group you want to assign. Click Save.
This is how your Register will look like after adding category groups. As you can see, the "Drinks (Non-Alcoholic)" and "Drinks (Alcoholic)" categories are under the "Beverages" category group. You can choose to hide or show categories with category groups.
