Do you ever get sick of hunting through a dropdown that has hundreds of items in no particular order.  I do!!  I've seen far too many LOB apps that feel the need to have hundreds items in a dropdown.  So this week, I created the expander dropdown to at least provide some organization to those massive dropdowns ...

And, for all of you still with the Sept CTP like me ... I'll try embedding the sample as a web browser application. Let me know how this works.

I removed the inline web browser app -- MD
