jquery - highlight menu items based on associated content -

-

i using jquery display content on website based upon menu item selection. each menu item has number attached matches content div container.

    $(".main-cat").hover(function() {     $(this).parent().find("div.arrow-right").remove();     $(this).after('<div class="arrow-down"></div>');     $(this).addclass('selected');     $(this).css('cursor', 'pointer'); },     function() {     $(this).removeclass('selected');     $(this).parent().find("div.arrow-down").remove(); });  $("#sidebar div").click(function() {     $("#real_0").hide();     $(".content_sub").hide();     var menuclass = $(this).attr('class');     menuclassp = menuclass.split(" ");     $("#real_" + menuclassp[1]).fadein('slow'); });

i trying add function highlight menu item corresponds currently *active* content.

what's best way write this? , can current code made cleaner?

add 

$(this).addclass('selected').siblings().removeclass('selected');

in click handler, , define selected class in css defines highlight style..

this add class selected clicked element (assuming active content), , remove siblings (the other divs in sidebar)
