Creating a Window List for menu

In an MDI form you can have several windows open.
Often, there is a menu option "Window" and if it is selected a list of open documents is displayed with a checkmark next to the active document.

Like in Word... you have

Window
New Window
Arrange All
Split
----separator
Here is a list of open documents.

How is this list created?
I was thinking you can't add menu items dynamically.

Thanks!

'From Megatron

'Make a menu called mnuTest with a SubMenu called mnuSub. 
'Make sure that that Index property for it is set to 0. 

'Now insert this code into a CommandButton on the Form. 


Private Sub Command1_Click()

    Load mnuSub(mnuSub.Count)   ' Loads another menu
    MyInt = mnuSub.Count - 1    ' Get the Index for the menu
    mnuSub(MyInt).Caption = Text1.Text ' Set the caption to whatever is in the TextBox.

End Sub

That should get you started.
