Creating a webform modal is quite simple and straight forward in Drupal 8. We only need the Webform module and some classes for the modal opening button: Download and install https://www.drupal.org/project/webform Create a webform
Several times in the last months we had the requirement to prepopulate a Drupal 8 webform with a parent entity ID from the URL. For example we had forms to register for events which we embedded on the node page as paragraphs or blocks and wanted to set an entity reference field to the node ID programmatically.
Leider musste ich heute in der Views Integration des Drupal Moduls "Webform" einen Fehler feststellen. Das Inhaltsfeld "Node: Webform submission count" ist in der aktuellen Webform Version 6.x-3.9 leider defekt.
