Does Polar Help Desk support custom fields?
Custom fields are not supported in the current version of Polar Help Desk however it uses a system of Incident Templates. Incident Templates allow you to select predefined values that will be selected for each element on Incident Form. For example you can disallow your customers to see Group field and these Tickets will be assigned to the group that is defined in the template. Each role can have permissions to see different templates (e.g. your customers could see one set of templates and your employees other).
