Need help coding mouse-over 'drop down' menu.

The way I would do it is add a !ShowMeterGroup to the dock icon to show all the subdocks (use LeftMouseUp or MouseOver depending on your preferences).

You will also create an invisible image (with alpha 0) that is exactly as big as the dock icon and all subdocks together and covers that entire area. Then you add a !HideMeterGroup as MouseLeaveAction to this invisible image. You can still have the !HideMeterGroup when clicking on one of the icons.

This way, if you hover/click on the dock icon, the submenu will pop up. It will close when you click on a launcher or when you leave the menu area without clicking anything.
