Editing device groups
Go to INVENTORY/EXTENDED and click the Device Groups tab.
The edit tree for device groups supports drag-and-drop to make modifications. This way you don't have to worry about modifying your device group tree later on. If you move an entry to a different position via drag-and-drop, all device and user relationships will be maintained.
To move a given context entry to a different position in the tree, simply mark the entry with a left mouse click, hold the left mouse button, and move the entry to the desired position. At the desired position, release the left mouse button.
