When configuring ticket types in calendar events, under Edit Ticket Information, it's possible to say "No limit" on both the total tickets available (Inventory Limit) and/or on the numbers any individual registrant can purchase (Limit Per Order).

When those settings are both No Limit, the resulting popup ticket description window should NOT include the lines at the bottom saying "Total number of tickets" and "Number of tickets available", and also the resulting "Order limit" third line. That is, that section should be automatically hidden in those windows when No Limit has been selected in the setup.

ALSO! Why is Calendar Events, or just Events, not available to choose in the field "Area of the Product" when submitting an idea?
