Display support desk in department

Pardon me, not clear about your requirement. Could you please add more details how you want to implement it?

Attachment feature: Duly noted. ??

there is a shortcode that shows all of the tickets, what about just specific department of all ticket?

If you want to display all the tickets only of specific department(s),then the feature is still not available from the plugin.
Noting this as a feature request.
