Re: Should disabled elements receive tab focus

So in the situation where there are two combo-boxes and a submit button on
a page, and the second combo box has no choices until the first combo box
has a selection made would you want that second combo to be in the tab
order? We were talking about adding a aria-disabled to the second combo box
until there are choices in the it, would make more sense to mark it
completely disabled?
