My JQuery CSS menu fails to hide

[muchehype]

I have created a simple jQuery Menu that expands on hover however unless the user hovers over another menu item or clicks else where in the page, the menu items do not get hidden. When you load another page using the links on the menu the page opens and leaves the menu expanded. How can I fix this? A fiddle with all the html and css can be found here. My jQuery code is here $(document).ready(function(){ $("#header_nav > li ").addClass("level1"); $("#header_nav > li > ul > li ").addClass("level2"); $("#header_nav > li > ul > li > ul > li ").addClass("level3"); $(".level1").live("hover",function(){ $(".level1").removeClass("main_menu_hover"); $(this).addClass("main_menu_hover"); var numberofChildren = $(this).find("> ul").children().length; if(numberofChildren != 0){ // Section 1 $(".level1").removeClass("active_main_menu"); $(this).addClass("active_main_menu"); // Section 2 $(".level1").find("ul").css("display","none"); $(this).find(" > ul").css("display","block"); // Section 3 $(".level2").removeClass("active_first_element"); $(".level2").removeClass("active_last_element"); $(".level2").removeClass("active_only_element"); // Section 4 if(numberofChildren == 1){ $(this).find("ul li:first").addClass("active_only_element"); }else{ $(this).find("ul li:first").addClass("active_first_element"); $(this).find("ul li:last-child").addClass("active_last_element"); } // Section 5 $(".level2 a").removeClass("sub_active"); $(".level2").removeClass("menu_hover"); }else{ // Section 6 $(".level1").find("ul").css("display","none"); $(".level1").removeClass("active_main_menu"); } }); $(".level2").find(".arrow-right").attr("href","javascript:void(0);"); $(".level2 > a").live("hover",function(e){ $("li").removeClass("menu_hover"); $(this).parent().addClass("menu_hover"); e.preventDefault(); }); $(".level2 a").live("click",function(){ $("li").removeClass("menu_hover"); if($(this).hasClass("sub_active")){ $(this).removeClass("sub_active"); $(".level2 > ul").slideUp(); }else{ $(".level2 ul").slideUp(); $(".level2 a").removeClass("sub_active"); $(this).addClass("sub_active"); $(this).parent().find("ul").slideDown(); } }); $(".level3 a").live("hover",function(){ if(!($(this).parent().hasClass("accordian_element_hover"))){ $(this).parent().removeClass("level3").addClass("accordian_element_hover"); } }); $(".accordian_element_hover a").live("hover",function(){ $(this).parent().addClass("level3").removeClass("accordian_element_hover"); }); });
