jQuery slide switch

Is there a way to do this with jQuery

$(this).toggle(
    "slide", 
    {
        direction: 'up',
        duration: 'slow',
        easing: 'easeOutQuart'
    }
);

but not have it "block" out the space first? As it stands I have a list of elements, and if you click a name it expands a section vertically. Unfortunately, it first kicks open a large block of empty space to make room for the animation.

Is there a way to do this animation where the box grows as the content grows, similar to "blind"?

Here is an example of the structure, however it doesn't utilize the slide animation, but the blind animation.

I have slightly changed the JavaScript of the example. Now the content slides out the right way...

$('.trials h4').bind(
    'click', 
    function() {  
            $(this).parents(".trials").children(".trial_container").slideToggle('slow');
               return false;
});
