The ListEntry object is a member of the ListEntries collection. The ListEntries collection includes all the items in a drop-down form field.
Use ListEntries(index), where index is the list entry name or the index number, to return a single ListEntry object. The index number represents the position of the entry in the drop-down form field (the first item is index number 1).
Use the Add method to add an item to a drop-down form field.
