Drop down menu can't be centre aligned

Has anyone found a way to make a drop down menu drop from the centre of the main menu item. There is not an option to do this in the sparkle controls, but just wondering if there is a way someone might have figured out? Is there a reason as to why you can’t do this?

The dropdown can be set to be the same width as the main menu item. This will make it all look centred.


Aha. Thank you. it is always something simple
