iPod-like jQuery drilldown menu provides easy navigation of complex and multi-level menus.

The menu sits within a fixed-size area, and when a node is selected, breadcrumb links appear above the menu options to both deliver feedback and allow quick access back to nodes higher up in the hierarchy.

An iPod-style slide transition helps providing the feelthat you’re moving forward into the data, or backward into higher-level data.

This menu is specifically useful in browsing deeply nested hierarchies, particularly those more than three levels deep. It also provides a more usable alternative to multi-level fly-out menus, which can present challenges to those with limited manual dexterity.
