Dynamic Ticket Forms

Dynamic Ticket Forms

Is it possible to create dynamic ticket forms?  The ticket form would have a dropdown that has the following choices: Shipping Questions, Returns, Sales Questions.  If a customer selects Shipping Questions the ticket form would have a field that says "Order Number". Alternatively, if the customer selects Sales Questions, the form would NOT show the Order Number field, and would only show basic fields like name, emails, etc.  

Is this possible with Zoho Desk?
