=head1 DESCRIPTION
This is a base Select input element.
=head1 METHODS
=over 4
=item visible
Select elements are not really visible if there are less than two choices
for them.
=cut
sub visible {
my $this=shift;
my @choices=$this->question->choices_split;
if (@choices > 1) {
return 1;
}

debug 'developer' => 'Not displaying select list '.
$this->question->name.' with '.
(@choices+0).' choice'.((@choices == 0) ? 's' : '');
return 0;
}
}
=item translate_default
This method returns a default value, in the user's language, suitable for
displaying to the user. Defaults are stored internally in the C locale;
this method does any necessary translation to the current locale.
=cut

my $this=shift;
# I need both the translated and the non-translated choices.

# Get the C default.
my $c_default='';

# Translate it.
foreach (my $x=0; $x <= $#choices; $x++) {
return $choices[$x] if $choices_c[$x] eq $c_default;
}
# If it's not in the list of choices, just ignore it.
return '';
}
=item translate_to_C
Pass a value in the current locale in to this function, and it will look it
up in the list of choices, convert it back to the C locale, and return it.
=cut
