Best javascript combo box? [closed]

Question

A combo box is an auto-complete text box that is also a dropdown (i.e., you can choose from a list if you prefer).

"Best" means combination of: stable, look/feel, API / customizability, maturity.

Answer 1

ExtJS has a very powerful combo box that provides dropdown, auto-complete, and filtering of choices. You can also enable pagination,

There are a number of extensions that provide additional capabilities, such as a Facebook style multi-select, or multi-select checkboxes.

Answer 2

I like the Yahoo UI Autocomplete widget. It does not provide the dropdown natively, but a dropdown button can be added with a few lines of code.
