  4. Create a command button in the form footer, and then set its properties as follows:

    Name: cmdDropdown
    Caption: Open Command Bar Dropdown
    OnClick: [Event Procedure]

  5. Set the OnClick property of the command button to the following event procedure:
    Private Sub cmdDropdown_Click()
   Dim cmdBar As CommandBar
   Dim cmdControl As CommandBarControl

   Set cmdBar = CommandBars("Test")

   For Each cmdControl In cmdBar.Controls
      If cmdControl.Type = 4 Then
         cmdControl.SetFocus
         SendKeys "{Down}", True
      End If
   Next cmdControl
End Sub
  6. In the Visual Basic Editor, click References on the Tools menu, and make sure the following reference is selected:

    Private Sub Form_Load(Cancel As Integer)
   Set focusBar = CommandBars.Add(Name:="Test")
   With CommandBars("Test")
      .Visible = True
      .Position = msoBarTop
   End With

   Set testComboBox = CommandBars("Test").Controls. _
      Add(Type:=msoControlComboBox, Id:=1)

   With testComboBox
     .AddItem "First Item", 1
     .AddItem "Second Item", 2
   End With
End Sub
  8. Set the OnUnload property of the form to the following event procedure:
    Private Sub Form_Unload(Cancel As Integer)
   For Each cmdBar In CommandBars
      If cmdBar.Name = "Test" Then
         cmdBar.Delete
      End If
   Next cmdBar
