Each of my article nodes has a set of 7 paragraphs elements that must be filled in. Is there some way the client does not have to add them manually each time?

Would I create a hook that adds some kind of auto (default) paragraph entity to the paragraph field when the node is created?

Is this technically possible?

I think I have seen once a module that allows to define default paragraphs via the url.

But I think I am wrong.

  • There is the prepopulate module drupal.org/project/prepopulate but I'm not sure if it works with Pragraphs out of the box Aug 29, 2018 at 10:22

Actually it is pretty simple. I have written a module with the following hook:

Hope that helps somebody. Pretty handy and user friendly when it comes to content that is mainly created through paragraphs elements.

You attach the field widgets to the node when the add form is opened.

function xxx_entity_prepare_form(EntityInterface $entity, $operation, FormStateInterface $form_state) {

    if("article" === $entity->bundle()){
        $bundles = ['article_navigation_banner', 'call_to_action_banner', 'author_information'];
        $entity_manager = \Drupal::entityManager();
        $langcode = $form_state->get('langcode');

        $field = $entity->get('field_ui_elements');

        $target_type = $field->getSetting('target_type');

        foreach ($bundles as $bundle_name) {
            // Create paragraph and display.
            $entity_type = $entity_manager->getDefinition($target_type);
            $bundle_key = $entity_type->getKey('bundle');

            $options = array(
                $bundle_key => $bundle_name,
                'langcode' => $langcode,

            if("call_to_action_banner" === $bundle_name){


            /** @var FieldableEntityInterface $paragraphs_entity */
            $paragraphs_entity = $entity_manager->getStorage($target_type)->create($options);

            // Field values.
