This article discusses Root Categories and their role in your Magento Go store. You will learn how to create new root categories and manage the root categories for your store views.
To understand what a root category is, it’s best to first describe the context in which it belongs. Attributes are organized into attribute sets. Attribute sets are used to describe products. Products are logically organized into categories. Categories are logically organized into a root category. It’s safe to say that the root category is the alpha category, the highest level in the hierarchy of your store catalog.
Magento Go allows you to create new root categories, but it’s important to know a few things before you start creating new ones. Be aware that your Magento Go store can have only one root category. This makes sense, because there can be only one alpha.
This has been a point of confusion for some who wonder why the products and categories in their second, or third root category are not visible in their store. The solution is simple: Link the root category that you want to use with your store in System > Manage Stores, as explained below.
