Context of Use

Applies to any site featuring a catalog of items, including e-commerce sites, news sites, portfolios, photography sites, and many more.

Task Flow

Users browsing for items of content (products, articles, or something else) traverse the catalog by following the three-step process of moving from a catalog to a gallery of items within that catalog wherein the user selects a specific item, and from the gallery to a content page wherein the user can decide if the item is indeed the item she wants.
