NAME
HTML::FormFu::Element::Checkboxgroup - Group of checkbox form fields SYNOPSIS
YAML config: --- elements: - type: Checkboxgroup name: subjects options: - [ 'Math' ] - [ 'Science' ] - [ 'English' ] DESCRIPTION
Convenient to use group of checkbox fields. Use the same syntax as you would to create a Select element optgroup to create Checkboxgroup sub-groups, see "options" in HTML::FormFu::Element::_Group for details. METHODS
options See "options" in HTML::FormFu::Element::_Group. values See "values" in HTML::FormFu::Element::_Group. value_range See "value_range" in HTML::FormFu::Element::_Group. auto_id In addition to the substitutions documented by "auto_id" in HTML::FormFu, %c will be replaced by an incremented integer, to ensure there are no duplicated ID's. --- elements: type: Checkboxgroup name: foo auto_id: "%n_%c" reverse_group If true, then the label for each checkbox in the checkbox group should be rendered to the right of the field control. Otherwise, the label is rendered to the left of the field control. The default value is "true", causing each label to be rendered to the right of its field control (or to be explicit: the markup for the label comes after the field control in the source). Default Value: "true" SEE ALSO
Is a sub-class of, and inherits methods from HTML::FormFu::Element::_Group, HTML::FormFu::Element::_Field, HTML::FormFu::Element HTML::FormFu AUTHOR
