+=item C<hidden_tag $name, $value, %attributes>
+
+Creates a HTML 'input type=hidden' tag named C<$name> with the value
+C<$value> and with arbitrary HTML attributes from C<%attributes>. The
+tag's C<id> defaults to C<name_to_id($name)>.
+
+=item C<checkbox_tag $name, %attributes>
+
+Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
+HTML attributes from C<%attributes>. The tag's C<id> defaults to
+C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
+
+If C<%attributes> contains a key C<label> then a HTML 'label' tag is
+created with said C<label>. No attribute named C<label> is created in
+that case. Furthermore, all attributes whose names start with
+C<label_> become attributes on the label tag without the C<label_>
+prefix. For example, C<label_style='#ff0000'> will be turned into
+C<style='#ff0000'> on the label tag, causing the text to become red.
+
+If C<%attributes> contains a key C<checkall> then the value is taken as a
+JQuery selector and clicking this checkbox will also toggle all checkboxes
+matching the selector.
+

+
+If C<%attributes> contains a key C<label> then a HTML 'label' tag is
+created with said C<label>. No attribute named C<label> is created in
+that case. Furthermore, all attributes whose names start with
+C<label_> become attributes on the label tag without the C<label_>
+prefix. For example, C<label_style='#ff0000'> will be turned into
