[jQuery] How to add a button for opening the list? [autocomplete]

Hello! Is it possible to add a button (like standard drop down list has) to open the list with all the results? I need two ways to select item by typing and selection from the list. If not, may be you can add this functionality to this plug-in? Thank you! :)
