Select disabled doesn't actually disable it

[jkehler]

When you set disabled on a select box it will grey it out and cause the hand with the stop icon to appear.

However, you are still able to interact with the select box. Clicking on it will bring up the options and you can select and deselect options and have the value state updated accordingly. Setting disabled should completely disable the widget.

Also is it possible to selectively disable items in a select box? I couldn't find any reference on how to do this in the documentation.
