Because forms may be split up into sections, this provides an easy URL to exactly the right section. Don't override this.
public function optionLink($text, $section, $class = '', $title = '') {
if (!empty($class)) {
$text = '<span>' . $text . '</span>';
}
if (!trim($text)) {
$text = t('Broken field');
}
if (empty($title)) {
$title = $text;
}
return l($text, 'admin/structure/views/nojs/display/' . $this->view->storage
->get('name') . '/' . $this->display['id'] . '/' . $section, array(
'attributes' => array(
'class' => 'views-ajax-link ' . $class,
'title' => $title,
'id' => drupal_html_id('views-' . $this->display['id'] . '-' . $section),
),
'html' => TRUE,
));
