What's New in jQuery UI 1.9?

The menu widget creates nestable menus, great for inline menus, popup menus, or as a building block for complex menu systems.

The spinner widget displays buttons to easily input numeric values via the keyboard or mouse. When used in combination with Globalize, the spinner supports numbers, currencies, and dates in hundreds of locales.

The tooltip widget shows additional information for any element on hover or focus, with support for static content and remote content loaded via Ajax.

The accordion, autocomplete, and tabs widgets have also received huge accessibility improvements. In addition, we've improved the APIs of several widgets, making them easier to use and creating more consistency across plugins.
