    </section>
{% endfor %}

Event::listen('backend.form.extendFieldsBefore', function (\Backend\Widgets\Form $form) {

    if (
        !$form->getController() instanceof \RainLab\Pages\Controllers\Index ||
        !$form->model instanceof \RainLab\Pages\Classes\Page ||
        $form->isNested
    ) {
        return;
    }

    if ($form->model->viewBag['layout'] == 'page') {

        $fields = Yaml::parseFile(themes_path('themes/YOUR_THEME/meta/nestead-repeaters.yaml'));

        $form->secondaryTabs['fields']['viewBag[sections]'] = [
            'tab'      => 'Sections',
            'type'     => 'repeater',
            'form'     => ['fields' => $fields],
            'cssClass' => 'secondary-tab ',
        ];
