I don't see the difference between this and a <select> element, except that the latter looks much better and works cross-platform. It doesn't offer any new functionality like auto-complete or validation. Am I missing something?
How are you going to float a value to the right inside of a native select value? How are you also going to style the value separately (font-weight, color etc)? All that is really available is optgroups vs. options.
