<!-- 
1. Put the "Country" field above the "Item" hierarchy in the rows
2. Expand any row, e.g., "Australia"
  * Note how the "Item" hierarchy rows are shown and we can further drill down
3. Now change the "Item" hierarchy to "Item/Category" in the Fields. 
  * Now, when we expand any row, e.g., "Australia", the Item/Category hiearchy does 
    not show and we cannot drill down.
4. Now change the "Item/Category" hiearchy to "Item/Color" in the Fields
  * Now, when we expand any row, e.g., "Australia", the Item/Color does show
    and we can further drill down
