One embodiment of the present invention provides a system that displays
and facilitates browsing through a sparse view of content items in a
hierarchy. First, the system receives a request to display a set of
content items with a common parent in a hierarchy. If the display area
has insufficient space to display some of the items, the system logically
splits the content items into a first subset of content items and a
distinct second subset of content items. The system then displays the
first subset, and displays a search element that represents the second
subset. When the system detects the selection of the search element by a
user, the system initiates a search operation that allows the user to
determine and select a desired item from the second subset.
