Yeah, I was hoping I wouldn't have to go that route. Ultimately if I can't figure this out I'll have to, but it seems unreasonable to not be able to delete one element from a form definition.

Why not?

To my mind, each screen is a different form, anything else is too complicated and reserved for client side javascript (ajax) manipulations :) I guess its a matter of perspective.

I'm not really up on HTML::FormFu::Manual::BasicConcepts, but remove_elements does appear to work 

#!/usr/bin/perl --
use strict;
use warnings;
use HTML::FormFu;
use YAML::XS qw( Load );
Main( @ARGV );
exit( 0 );

sub Main {
    Fain();
    print "\n", '#' x 33 , "\n";
    Fain( { dependOnMe => "if i'm not here, remove fooRadiogroup" } );
}


sub Fain {
    my $cgi = shift;
    my $form = HTML::FormFu->new;
    my $data = Load(<<'__YAML__');
---
elements:
    - type: Text
      name: foo

    - type: Text
      name: dependOnMe

    - type: Radiogroup
      name: fooRadiogroup
      options:
        - value: 1
          label: 'First'
          attributes:
            myattr: 'escape&attr'
          label_attributes:
            myattr: 'escape&label'
          container_attributes:
            myattr: 'escape&container'
        
        - value: 2
          label: 'Second'
          attributes_xml:
            myattr: 'noescape&amp;'

    
__YAML__
    
    
    $form->populate($data);
    $form->process( $cgi );
    
    if( not $form->valid('dependOnMe') ){
        my $pariah = $form->get_field( name => 'fooRadiogroup', type =
+> 'Radiogroup' ) ;
        $form->remove_element( $pariah );
    }
    print $form;
}

__END__
