Hierarchies Pattern Set
 
Description
Return to Top

The Categorized Content pattern groups information into main categories and limits each view to a group that spans two levels of hierarchy. There are no interface controls to expand or collapse branches. Categorized content is a familiar display for Web users and does not require component-level scrolling to see objects within the hierarchy. This pattern is appropriate for use by casual users who may prefer categorized content to less familiar hierarchical display components. Categorized content is often followed by Browse patterns that display categories and items.

Pattern Sample

The user drills through levels of categories from general to more specific. Breadcrumbs build as the user drills down, providing a way to navigate back up through categories. When items within the categories appear with categories, use the Browse patterns.
