 Client
     - Client needs to tell the server which form of list is required, i.e. it's client window size when fetching a list
-   
+        - viewport="XS" I think would be sufficient
 
 Server
     - Server needs to accept a parameter from the client when a grid list is fetched that tells it if it needs to send a single column templated list 
-   
+        - viewport="XS" I think would be sufficient
