=head1 NAME
Reaction::UI::Widget::Field::ChooseMany - Choose a number of items
=head1 DESCRIPTION
See L<Reaction::UI::Widget::Field::Mutable>
This needs a refactor to not be tied to a dual select box, but ENOTIME
=head1 FRAGMENTS
=head2 action_buttons
Sets the following events by the name C<event_id_$name> as arguments with their viewport
event ids as values:
add_all_values
do_add_values
do_remove_values
remove_all_values
=head2 current_values
Renders the C<hidden_value> fragment to store the currently selected values either once
for every item in the viewport's C<current_value_choices> (with the C<field_name> argument
set to the viewport's event id for C<value>. Or, if no current values exist, uses the
C<no_current_value> event id from the viewport and sets the topic argument C<_> to 1.
=head2 selected_values
Sets C<event_id_remove_values> to the viewport's event id for C<remove_values> and renders
the C<value_option> fragment over the viewport's C<current_value_choices>.
=head2 available_values
Sets C<event_id_add_values> to the viewport's event id for C<add_values> and renders
the C<value_option> fragment over the viewport's C<available_value_choices>.
=head2 value_option
Sets the C<option_name> argument to the current topic argument's C<name> key and the
C<option_value> to the current topic argument's C<value> key.
=head2 hidden_value
Sets C<hidden_value> to the current topic's C<value> key.
=head2 field
renders C<available_values>, C<action_buttons>, C<selected_values> and C<current_values>
=head1 LAYOUT SETS
=head2 base
share/skin/base/layout/field/mutable/choose_many.tt
This layout set provides a table containing two lists separated by action buttons that
allow the user to add values from the available list to the selected list.
=head2 default
share/skin/default/layout/field/mutable/choose_many.tt
Same as in the C<base> skin, except that after each action button a C<br> element will
be rendered.
=head1 AUTHORS
See L<Reaction::Class> for authors.
=head1 LICENSE
See L<Reaction::Class> for the license.
