DESCRIPTION

       "filters()" and "filter" can be called on any form, block element (includes fieldsets) or
       field element.

       If called on a field element, no "name" argument should be passed.

       If called on a form or block element, if no "name" argument is provided, a new filter is
       created for and added to every field on that form or block.

       See "FORM LOGIC AND VALIDATION" in HTML::FormFu for further details.

METHODS

   type
       Returns the "type" argument originally used to create the filter.

   localise_args
       Provide arguments that should be passed to localize to replace "[_1]", "[_2]", etc. in the
       localized string.

   parent
       Returns the HTML::FormFu::Role::Element::Field object that the filter is associated with.

   get_parent
       Arguments: \%options

       Traverses the parent hierarchy, returning the first parent that matches the supplied
       options.

   form
       Returns the HTML::FormFu object that the filter's field is attached to.

   name
       Shorthand for "$filter->parent->name"
