How do I restrict customers from editing the ticket properties after a ticket is submitted?

We have recently refreshed our branding across our offerings and changed the names of our pricing plans. If you have signed up before Aug 9, 2021, please click Previous plans to view your applicable plans.
We assure you that this change will not impact your product experience, and no action is required on your part.

You can use the below-displayed code to restrict the customer from editing the ticket fields after a ticket is submitted. 

Please navigate to Admin--> Channels > Portals -->Customize portal-->Layout & pages-->Portal pages-->paste the below code under the Ticket details section,

<script>

  jQuery('#portal_ticket_form .controls').each(function() { 

    jQuery(this).children().attr('disabled','disabled'); 

  });

  jQuery('#helpdesk_ticket_submit').attr('disabled','disabled')

</script>

This would be possible only from the Estate plan onwards in Freshdesk.
