In the Chap 7 discussion of IS_IN_BOOT,
<http://web2py.com/books/default/chapter/29/07/forms-and-validators#Database-validators>
there's a paragraph beginning
"If you want the field validated, but you do not want a drop-down, you must
put the validator in a list
[...] Occasionally you want the drop-down "
Does that section help with your question?
