How to make a drop-down search field in Flex

I think everyone has seen the google search field where it shows you string matches of what the user types in, and the choices appear in a dropdown just underneath the text field.

I would like to make something similar in my application, but I'm not sure how to replicate the same visual interface. Should I use a mx:ComboBox, make it editable, and somehow find a way to make the dropdown remain visible?

Or are there better ways? Any suggestions would be greatly appreciated.
