To move a category or product from one location in the hierarchy to another, drag the item from its current location in the catalog tree to the desired location.
From the ATG Control Center main navigation menu, select Catalog Management > Catalogs.
Select the category or product in the catalog tree.
With the cursor positioned over the item, hold down the left mouse button.
Drag the item on top of the category you want to place it in.
Release the mouse button.
Select File > Save.
If you hold down the Ctrl key while dragging the item, the item becomes the child of both its original parent category and the new category you drag it to. This operation does not create a new copy of the item.
