[jQuery] Making a Sliding Tab Menu

Ok so im trying to make a sliding tab menu, The menu is already made
with animations and such, however now im trying to integrate the menu
with the Divs i have for each menu item. Would anyone know of any
tutorials that would help accomplish this? I really just need
something to start me off..

Basically on click i want the current selected item and div to fadeOut
to the left and the newly selected to fadein from the right... any
help would be appreciated thanks

JQUERY

$('span').click(function(event) {
        if ($(event.target).hasClass('selected'))
        {
                window.alert("already selected");
                event.stopPropagation();
        }
        else
        {
                $(event.target).addClass('selected');

                event.stopPropagation();
        }
});
