Embed Drupal 8 Contact Forms into a page

Parent Feed: 

Currently the core module Contact form only gives you an accessible URL that you can visit too see your form. There are plenty use cases where you instead would like to embed it into a page, a node, etc.

First we have the Contact Block module which allows you to use blocks to display contact forms.

The second option is to do it programmatically. So for example if we would like to add a form to all pages, we could preprocess the page hook_preprocess_page(&$variables) and then:

  // Get feedback form to be rendered on all pages.
  $message = \Drupal::entityTypeManager()
          'contact_form' => 'feedback', // The machine name of the form.
  $form = \Drupal::service('entity.form_builder')->getForm($message);
  $vars['feedback_form'] = $form;

Now we have a feedback_form variable we can simply output in our page.html.twig template.

If you want the form to be dynamic without a page reload, take a look at the Contact ajax module which works just fine even though it's in beta!
