This is an example from my current project.

$contenxt->stash->{group} is populated by a Chained action.

This is added to the Select element, so $self->parent refers to the
Select element.
    type: Select
    name: foo
    plugins:
      - CAMS::SelectPanel


package HTML::FormFu::Plugin::CAMS::SelectPanel;
use strict;
use base 'HTML::FormFu::Plugin';

sub pre_process {
    my ($self) = @_;

    my $context = $self->form->stash->{context};

    my $group = $context->stash->{group};

    my $panels = $group->search_related(
        'group_panel_rel',
        {},
        {
            order_by => ['order_id'],
        },
    );

    my @options;

    for my $panel ( $panels->all ) {
        push @options, [ $panel->id, $panel->name ];
    }

    $self->parent->options( \@options );

    return;
}
