> I do not really understand what is the problem with flexible <select> implementation in browser. There isn't a problem. Your flexibility is just in the wrong place—the flexibility is on the side of the user and user agent, e.g. to manifest and interact with a "<select multiple>" input method however best for the device that the user is looking at the form with. The fact that it's not actually codified anywhere exactly how "<select multiple>" should work is a good thing. Your approach does away with that.
