jQuery Sexy Combo wrapper height problem

I have a height problem with Sexy Combo ( google 开发者_如何学运维'Sexy Combo' ), a jQuery editable drop-down list.

The author of the script didn't optimized the drop-down to look good if it is placed in a popup which is not visible on page load. After loading the popup and clicking on the drop-down, the list doesn't show -- FireBug says it's height is 0px.

I was reading the script but I couldn't find how to make the list-wrapper with fixed height. If someone would like to help, this is the Sexy Combo script.

Thanks in advance...

Fixed... I've changed the pop-up property from display:none to visibility:hidden.
