Abstract: An improved user interface in which related items are organized in a manner that is intuitive to a user, and ultimately results in the number of navigational steps performed by the user to identify desired items being reduced, is described herein. For example, instead of having a user interface display a large number of related items, a recommendation system can identify a single item related to an item initially selected by the user that is associated with one or more factors a user likely finds important in deciding which item to select, and produce data that results in a user interface that displays the single related item. Optionally, the user interface can display the single related item in an above-the-fold (ATF) portion of the user interface such that the single related item is visible to a user without the user having to interact with the user interface.
