If you set ListModelList to it, All the content will send to client side and process at client side, this is pretty fast with few items but will cause performance issue at client side if there are lots of items (e.g., 40000 or more) in model. If you set ListSubMmodel to it, The content of drop-down list will not rendered to client side, and is blank without input, server will provide the 'matched' content after user input, this will cause some delay at client side cause by the server processing time and network transfer time.
