How to use jQuery Selected single selection with text box

I want to do something very similar to jQuery Autocomplete, but with a <select>list and use Chosen instead.

The problem is that I want it to function as autocomplete text input (instead of having a drop-down list that you have to click before entering a query).

The selected library currently only allows this type of input for multiple samples. Is there a way to do this for one choice?

Refer to the multiple choice example to see what I mean:
