At Filament Group, we build elegant communications and interactions that help people understand, work, and collaborate effectively across a variety of media - from web sites to wireless, to interactive exhibits and print.

the iPod-style menu provides easy navigation of complex nested structures with any number of levels. The entire menu sits within a fixed-size area, and when a node is selected, by default a "Back" link appears below the menu to allow navigation to previous (parent) menus, or set options to show breadcrumb links above the menu options to both deliver feedback and allow quick access to nodes higher up in the hierarchy. A lateral iPod-style slide transition reinforces the notion that you're moving forward into more granular data, or backward into higher-level data. This menu is specifically useful in traversing 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.

Understanding jQuery UI widgets: A tutorial Last updated 2009-06-07 This was written largely to help me make sense of using UI to create my own widgets, but I hope it may help others. "Widget" to me means a user-interface element, like a button or something more complicated like a popup date picker, but in jQuery UI terms it means a class, members of which are associated with HTML elements; things like Draggable and Sortable. In fact, not everything that I would have called a widget uses $.widget; the UI datepicker does not.
