What is a Category Definition?
Category definitions describe the categories in your catalog. A category can have one or more properties, such as name, description, and image. The properties for the category define what you can use to display on the pages of your site or items for which your customers can search when they read the site. You define these properties in the category definition. For example, if you want to store information about manufacturers, and then organize products by manufacturer, you can create a Manufacturer category definition that would include different properties, such as Manufacturer Name, Country/Region, Address, and Contact Person.
After you create a category definition, you can create categories based on that category definition.
