jQuery UI, built on top of jQuery, is a complete set of behaviors and components that can be used in building Rich Internet Applications. Behaviors and components included in jQuery UI include drag-and-drop, resizing, mouse-sorting, mouse-selecting (click-select, shift-select, ctrl-select, lasso select), dialogs, sliders, tabs, trees, grids, toolbars and menus.

Each component adheres to a consistent standard across API, design, behavior and theming. This minimizes the surprise and makes learning all of them as easy as learning one. Just as with jQuery, there is a plugin system in jQuery UI that allows users to easily modify/extend existing components, as well as create your own. jQuery UI is also built with themes and supports custom themes, for consistency with existing sites/applications.


This session covers how jQuery UI is designed and how it leverages the power, flexibility, and expressiveness of the jQuery API. A live demonstration shows you how to use some of the more common jQuery UI behaviors and components to create rich interactivity.
