Thank you for the link.   But sadly the control requires 8.5.2 and we are only on 8.5.1.

 

 

Before you drop that control out from your list, make sure that it really does require 8.5.2. I would still test it in 8.5.1.

 

I hope you find another solution.

Extension Library requires also the 8.5.2 so you are out from those libraries aswell. Too bad, since it wouldn't be that hard to create a pick list custom control of your own with those tools.
