title: jquery position with collision. add class when collision detected
body: <p>I am using jquery-ui's autocomplete box with collision to display the autocomplete either above or below the input. What I would like is to add a class to the autocomplete element if a collision is detected so i can customize the css a bit if it is above vs below. This seems like it should be simple enough to do, but I can't seem to figure out any way to make it happen.</p>
