You could do something like this (run on exit from the dropdown)
Dim NewItem As String
With ActiveDocument.FormFields("Dropdown1")
If .result = "Other" Then
NewItem = InputBox("Enter the item that you wish to use", "New Item")
.DropDown.ListEntries.Add NewItem
.result = NewItem
End If
End With

Hope this helps.
