HTML::FormHandler::Field::Multiple - multiple select list

version 0.40057
=head1 DESCRIPTION
This is a convenience field that inherits from the Select field and
pre-sets some attributes. It sets the 'multiple' flag,
sets the 'size' attribute to 5, and sets the 'sort_options_method' to
move the currently selected options to the top of the options list.
