Studioware allows you to enter in "Categories" on the administrative page. Currently, you can define Class Categories. When you Add/Edit a class, you will be allowed to affiliate one or more categories with a class.
Categories are useful for your customers when they need to search for a class on the Business Portal. Your customers can enter in the Category name to find class.
For example, suppose you have 5 classes that are related to a particular curriculum. You could create a category labeled "Introductory", and affiliate the 5 classes with that category. Next, you could inform your customers to search for "Introductory" on your business portal, and the 5 classes would appear.
