I have added a "NewMenuItem" to the main commandbar. Below that I have added
two SubMenuItems with no assigned OnAction events.

Set Item = CommandBars(1).Controls("NewMenuItem").Controls.Ad d
Item.Caption = "&SubItem1"
Item.BeginGroup = False

Set Item = CommandBars(1).Controls("NewMenuItem").Controls.Ad d
Item.Caption = "&SubItem2"
Item.BeginGroup = False

What I want to do is be able to select the "SubItem1" and create multiple
menu items below it.

Thanks.
