slimMenu is a lightweight jQuery plugin, which is made to create responsive and multi-level navigation menus on the fly.
jQuery Navobile is a jQuery plugin that makes mobile navigation easy. Navobile uses CSS to apply CSS3 translations, Mobile device detection and fixing the position of nav.
It uses touch events and CSS3 transitions for the best possible performance. It also contains a “clever” workaround that makes it possible to transition from height: 0 to height: auto, which isn’t normally possible with CSS3 transitions.
