jPanelMenu is a jQuery plugin that creates a paneled-style menu (like the type seen in the mobile versions of Facebook and Google, as well as in many native iPhone applications).

Animation is handled by CSS transitions. CSS transitions are hardware-accelerated on supporting devices, so the animations are silky smooth. For browsers that do not support CSS transitions, the jQuery animation engine is used as a fallback.

Use jRespond to enable and disable jPanelMenu at the appropriate breakpoints, creating a truly great responsive experience.
