Change jQuery UI Autocomplete Position - Pop up, instead of down

Question

I am placing an autocomplete box at the bottom of my page and I would like the results to pop up OVER the text box, instead of below. How can I do this?

Seems as if I've been able to answer my own question already. I'm open to a better solution if someones got it. I added this to the autocomplete start up.. essentially it repositions the box on open to a new offset.

open: function(event, ui) {
    var autocomplete = $(".ui-autocomplete");
    var oldTop = autocomplete.offset().top;
    var newTop = oldTop - autocomplete.height() - $("#quick_add").height() - 10;

    autocomplete.css("top", newTop);
}
