Success! Looks like we've fixed this one. According to our records the fix was applied for
a recent build.
beta1: Add select field cls to overlay
Not sure if this should go into the feature request forum,
but anyway, right now you can't create two different styles for two different select field's overlays.
Maybe it's possible to add the select field custom "cls" to the "cls" of the overlay in "getTabletPicker".
I think there is a lot we can do to increate the configurability of the Select field.

There will be new configurations to do this in the next release: defaultPhonePickerConfig and defaultTabletPickerConfig.
