I personally think stickUp, is overkill. I can achieve the same effect with 5-6 lines of jQuery code. If you are looking for an example see http://xcartnext.com

/*
 *  Floating Menu
 */

var $menu = $('#main-wrapper');
    menuOffsetTop = $menu.offset().top;
    
$(document).bind('ready scroll', function () {
    var docScroll = $(this).scrollTop();

    if (docScroll >= menuOffsetTop - 65) {
        $('#page').addClass('fixed_menu');
    } else {
        $('#page').removeClass('fixed_menu');
    }
});
