JQuery slideToggle

[OAFC_Rob]

I have a funcytion which get the height of the div and I want this function to be running while the slidToggle effect is taking place, anyone have any ideas?

 

If I run it before it looks gittery, if I run with the callback function it looks jittery.

 

This is the function taken out of the function and running at the callback. So ideally it should be a smooth transition with the div sliding down and the height of another div adjusting. 

 

$('.accordionHeader').click(function() 
    {
        
        $(this).toggleClass('accordionHeaderActive');
        $(this).next().slideToggle('slow', function(){
            contentHeight = $(".content").outerHeight();
            height = (contentHeight-500);
            //$("#adjuster").animate({"height" : height},"fast");
            $("#adjuster").css('height', height);   
        });
        
        return false;
    }).next().hide();
