Not sure if this is possible but can you load and unload into a div on a jquery toggle?
something a bit like this?
$("#IDOFCLICK").live('click',function(){
$(this).toggleClass("active").('#IDOFDIVTOLOAD').load('PAAGETOLOAD').slideToggle("slow");
});
if you can I guess the above is not right, but, how would you also unload on the "reverse" toggle?
