Sub CreateMenu()
' creates a new menu.
' can also be used to create commandbarbuttons
Dim cb As CommandBar, cbMenu As CommandBarControl, cbSubMenu As CommandBarControl
DeleteCommandBar ' delete the custom menu if it already exists
' create a new menu bar to replace the built-in menu bar
Set cb = Application.CommandBars.Add("MyCommandBarName", msoBarTop, True, True)
' create a new menu on an existing commandbar (the next 6 lines)
Set cbMenu = cb.Controls.Add(msoControlPopup, , , , True)
With cbMenu
.Caption = "&Mi menú"
.Tag = "MyTag"
.BeginGroup = False
End With
' or add to an existing menu (use the next line instead of the previous 6 lines)
'Set cbMenu = Application.CommandBars.FindControl(, 30007) ' Tools-menu
If cbMenu Is Nothing Then Exit Sub ' didn't find the menu...

' add menuitem to menu
With cbMenu.Controls.Add(msoControlButton, 1, , , True)
.Caption = "&MenuItem1"
.OnAction = ThisWorkbook.Name & "!Macroname"
End With
' add menuitem to menu

.Caption = "&MenuItem2"
.OnAction = ThisWorkbook.Name & "!Macroname"
End With

' add a submenu
