How to old multiple container in item of extjs panel. 

A:

Before add container multiple times in to your panel. Check that container 
you are adding does not have id or itemId as a config property.

So if you want to add that container multiple time you can use that container
with different itemId.
Otherwise it will add only one container and other added container will not
displayed on GUI.
