Hiding the Priority field in the ticket submission form

You can set, per department, a default priority that will be automatically selected in the Priority field when choosing the department in the ticket submission form (Submit Layout menu item). This means that, if you wish to not allow your users to choose a priority for the tickets they are about to submit, you can do so by hiding the Priority field using the following CSS rule:

This rule can be added in one of your Joomla! template CSS files, preferably a file that is not overwritten upon an update. For example, if you're using a default Joomla! template, you can add it in the user.css in Joomla!'s 3.x Protostar, or Joomla!'s 4/5 Cassiopeia. Further details here.
