public class ComboBox
extends Select

A filtering dropdown single-select. Suitable for newItemsAllowed, but it's turned of by default to avoid mistakes. Items are filtered based on user input, and loaded dynamically ("lazy-loading") from the server. You can turn on newItemsAllowed and change filtering mode (and also turn it off), but you can not turn on multi-select mode.
