Ok, thank you for your responce, 2 tiere I think is what im talking about, Collection\name1\subName1,
So Theme, is where i need to look at, "Layout.xml" ?
<menu> Parameters ?
<menu>
  <itemDefaults/>
  <item/>
</menu>
This is example in your documentation, 
I see within MENU and /MENU, 
<menu menuIndex="1"  there is 0, so by adding a "2" allow for another tiere, hope im understanding it.
