Grouping of ListDataSource

[mrcarver]

CG Gurus,

I have a CGDropDown that I have been filling using the "Items.AddOption", which is grouped. But this list is quite large and slowing the load time down considerably. If at all possible would prefer to use a data bound list source to improve on the speed. How can I use the ListDataSource and still have the resulting list grouped? The objective of course is to provide a dropdown list that is groupable and searchable via async.

Please Advise.

Monte Carver
