There is no such animal within Word. You could create a userform with a multi-column list or combobox or you can fudge and create a pseudo multi-line content control dropdown box.
Using the CC properties dialog, title the CC "Address", enter the person's name as the Text to Display and enter the full address as the value separated with "|" e.g.,
Jim Smith Jim Smith|123 Eaton Street|Suite 9A|Boston MA 12345
Use this code on CC exit:
Code:
Private Sub Document_ContentControlOnExit(ByVal CC As ContentControl, Cancel As Boolean)
Dim arrParts() As String
Dim lngIndex As Long
Select Case CC.Title
Case "Address"
If Not CC.ShowingPlaceholderText Then
For lngIndex = 2 To CC.DropdownListEntries.Count
If CC.Range.Text = CC.DropdownListEntries(lngIndex).Text Then
arrParts = Split(CC.DropdownListEntries(lngIndex).Value, "|")
Exit For
End If
Next lngIndex
CC.Type = 1
CC.MultiLine = True
For lngIndex = 0 To UBound(arrParts)
Select Case lngIndex
Case 0: CC.Range.Text = arrParts(lngIndex) & Chr(11)
Case UBound(arrParts): CC.Range.Text = CC.Range.Text & arrParts(lngIndex)
Case Else: CC.Range.Text = CC.Range.Text & arrParts(lngIndex) & Chr(11)
End Select
Next lngIndex
CC.Type = wdContentControlDropdownList
End If
End Select
End Sub
