NAME
HTML::Widget::Element::RadioGroup - Radio Element grouping

SYNOPSIS
    my $e = $widget->element( 'RadioGroup', 'foo' );
    $e->comment('(Required)');
    $e->label('Foo'); # label for the whole thing
    $e->values([qw/foo bar gorch/]);
    $e->labels([qw/Fu Bur Garch/]); # defaults to ucfirst of values
    $e->comments([qw/funky/]); # defaults to empty
    $e->value("foo"); # the currently selected value
    $e->constrain_values(1);

DESCRIPTION
RadioGroup Element.

As of version 1.09, an In constraint is no longer automatically added to RadioGroup elements. Use "constrain_values" to provide this functionality.

METHODS

  comment
Add a comment to this Element.

  label
This label will be placed next to your Element.

  legend
Because the RadioGroup is placed in a "fieldset" tag, you can also set a </legend> value. Note, however, that if you want the RadioGroup to be styled the same as other elements, the "label" setting is recommended.

  values
List of form values for radio checks. Will also be used as labels if not otherwise specified via labels.

  checked

  value
Set which radio element will be pre-set to "checked".

"value" is provided as an alias for "checked".

  labels
The labels for corresponding "values".

  constrain_values
If true, an In constraint will automatically be added to the widget, using the values from "values".

  retain_default
If true, overrides the default behaviour, so that after a field is missing from the form submission, the xml output will contain the default value, rather than be empty.

CSS

  Horizontal Alignment
To horizontally align the radio buttons with the label, use the following CSS.

    .radiogroup > label {
      display: inline;
    }

  Changes in version 1.10
A RadioGroup is now rendered using a "fieldset" tag, instead of a "label" tag. This is because the individual radio buttons also use labels, and the W3C xhtml specification forbids nested "label" tags.

To ensure RadioGroup elements are styled similar to other elements, you must change any CSS "label" definitions to also target the RadioGroup's class. This means changing any "label { ... }" definition to "label, .radiogroup_fieldset { ... }". If you're using the "simple.css" example file, testing with firefox shows you'll also need to add "margin: 0em;" to that definition to get the label to line up with other elements.

If you find the RadioGroup "fieldset" picking up styles intended only for other fieldsets, you can either override those styles with your "label, .radiogroup_fieldset { ... }" definition, or you can change your "fieldset { ... }" definition to ".widget_fieldset{ ... }" to specifically target any Fieldset elements other than the RadioGroup's.

Previously, if there were any errors, the label tag was given the classname "labels_with_errors". Now, if there's errors, the RadioGroup "fieldset" tag is wrapped in a "span" tag which is given the classname "labels_with_errors". To ensure that any "labels_with_errors" styles are properly displayed around RadioGroups, you must add "display: block;" to your ".labels_with_errros{ ... }" definition.
