Little search on a dropdown list

Hi Guys,

I have a long list of categories, and I was wondering if its possible to place a little search bar on the category dropdown list, so visitors can easily type in their category, rather than scrolling through a long list looking for the category they’re interested in.

Here’s an example of what I’m trying to achieve.
