The first option in a dropdown list is normally the placeholder text and if you set the value to "" or vbNullString as in Greg's macro the placeholder text should be displayed. You can however select any item in the list using the following -
Code:
Case Is = wdContentControlDropdownList
oCC.Type = 1
oCC.Range.Text = vbNullString
oCC.Type = wdContentControlDropdownList
oCC.DropdownListEntries.Item(2).Select
- here the item after the placeholder text.
or even
Code:
Case Is = wdContentControlDropdownList
oCC.DropdownListEntries.Item(2).Select
Have you considered saving the form as a template from which new documents are created? Then as each new document matches the template there should be no need to clear the form.
