Recently I was asked to implement search in long dropdowns. Our customer got stressed each time when he had had to find a product in the loooong list.
I tried to search for a solution in the Internet and there are at least two fancy ones. But one of them is very slow for long lists (well, we do need to search in long lists first of all) and the other one is simple but doesn't allow to select items manually.
So I ended up with very easy solution

Quite big list of lightboxes - very glamour effects of showing photos in pop-up windows. I might use one of these later :)
