The term navigation refers to the methods shoppers use to move from page to page throughout your store. The main menu, or top navigation of your store is actually a list of category links, and provides easy access to the products in your catalog. 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. To learn more about category display options, see: Display Settings.
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 a list of products in the category. You can also create special designs for category pages that are active only for a specific period of time such as for a holiday or promotion.
