DropDownList still doesn't support optgroups?
Am I crazy, or am I seeing that you still can't do optgroups in a DropDownList in v2 of ASP.NET? It's one thing making the controls XHTML compliant, quite another having them do everything the XHTML schema will allow. You can't even inherit ListItem to hack out your own version. Lame!
Not that it's hard to implement, but come on guys... don't take short cuts!
