try library: http://www.berriart.com/sidr/

or if don't need animations , want build hand, try this:

$("#id-of-submenu-link-that-hides-menu").on('click',function() {     var menu = $('#id-of-menu-to-hide');     menu.css('position','absolute');//if have positioned other way     menu.css('margin-left','-280px'); });  $("#id-of-link-to-show-menu").on('click',function() {     var menu = $('#id-of-menu-to-hide');     menu.css('position','inherit');//or whatever     menu.css('margin-left','0'); }); 

you may or may not need mess position of menu - depends on how have positioned. try , without positioning change if you're not sure.

hope helps. let me know if of doesn't make sense , luck!
