Menu
Is there any way to display the Autocomplete result set above the text input?
The problem is that I am using it in a lighbox application. The background element being set to 100% of the pages' height and width, it will naturally not expand with its content. So if the content above the text box increases so much that the input is forced towards the bottom of the page, and then the user types something into it, the autocomplete menu appears, and the input being towards the end of the page, the menu causes scrollbars to appear
Since the background element (dark colored) won't expand to accommodate it, as the menu is absolutely positioned, it looks visually ugly that the bottom of the page appears white (consistent with the actual page's color) while the top of the page dark.
So is there anyway to accomplish this, that prior to the autocomplete menu appearing, the position of the input should be checked. If it is, say, at more than 300px from the top, then the menu should appear above the input? This is the code:

You'll want to add an open function to your autocomplete options. From there, you can adjust the results based off of its current position and height. This should get you close:
open: function(event, ui){
var $input = $(event.target),
$results = $input.autocomplete("widget"),
top = $results.position().top,
height = $results.height(),
inputHeight = $input.height(),
newTop = top - height - inputHeight;
$results.css("top", newTop + "px");
}
