drupal 8 form add hash fragment to submit path

Because we always want to go to the same place on the page when using the mini form, that is, this destination does not have to be dynamic, this works great:

    $form['#action'] = "#snapshot-mini-form";

This sends the reader back to where they were in article—the form—after submit.

drupal 8 send hidden form element value same as options array
hidden form element value same as checkboxes element
php make array keys same as values

  $this->newsletters = array_combine($newsletters, $newsletters);
