Show closed form as read only form I'm working on a Drupal 8 project where I need to show closed webforms as read-only form (without submit button and possibility to answer them), but Webform behaviour doesn't fit my need, as it only display a message "Sorry...This form is closed to new submissions." without displaying the webform. 

Is their any way/hook that will allow me to display these closed webform?
You would need to not close the form but use hook_webform_submission_form_alter() to change all elemnts to be readonly and hide the submit buttons.
