Navigation by Category
The category structure of your catalog is one of the main ways people find products while shopping in your store. The term navigation refers to a variety of methods shoppers use to move from one page to another in your store. The main menu, or top navigation of your store is actually a list of categories. You will also find categories in the breadcrumb trail that runs across the top of most pages, and in the layered navigation that appears on the left side of some two- or three-column pages. These are all examples of how categories can be used to navigate throughout your catalog.
For a product to be visible in your store, it must be assigned to at least one category. Each category can have a dedicated landing page with an image, static block, a description, and list of products. You can also create additional designs for your category pages that become active for a specific period of time.
