As far as I know you can only bind a single xml node to a content control.

I've had no problem binding a node to a dropdown CC and the method is no different to binding a node to a plain text CC. The only complexity with dropdown CCs is that each entry has a display name and a value. The value is what gets stored in the XML node.

Are you trying to populate the dropdown CC options with multiple nodes? As far as I'm aware, that isn't dynamic and you would need to use code to clear the dropdown list and repopulate it from the xml data. This is not mapping.
