HTML::FormHandler::Widget::Field::CheckboxGroup - checkbox group field role
=head1 VERSION
version 0.40057
=head1 SYNOPSIS
Checkbox group widget for rendering multiple selects.
Checkbox element label class is 'checkbox', plus 'inline'
if the 'inline' tag is set.
Options hashrefs must have the keys 'value', and 'label'.
They may have an 'attributes' hashref key. The 'checked'
attribute should not be set in the options hashref. It should
be set by supplying a default value or from params input.
See L<HTML::FormHandler::Field::Select> for documentation on
select fields and options.
