Yes, I'm using the latest version. Like I said, I don't know how to do this so I do not have an example.
In the end I just used the MultiSelect and some extra code on the server to get it working.
But I would like to see an example of the MultiSelectFor.
So the data from my list is in Model.Profiles and the result from the list should be bound to Contractor.Profiles (this is a collection generated by EF)
