Configuring your Catalog views allows you to define exactly how the catalog layout looks for each of the views, and to select the fields you wish to display and hide others.
You can also create Filters, which are secondary groupings of your items by criteria which you define, to make groups of products quickly accessible for reps based on price, inventory, promotions, sub-categories, and more. For detailed instructions see this article: Manage Filters.
You can customize the properties that are displayed for each view in the catalog (Small, Medium, Large, Gridline view, Matrix view). To do so, see the detailed instructions in the article: Configure Catalog Views
