mailto argument in event custom field

Hi, is it possible that in an created event custom field the mailto argument is true?
I did´nt found a way to do this in xml file (fields.xml)

I solved it.
I added in the event_properties.php the FILTER_VALIDATE_EMAIL to check if in the custom fields is an valid e-mail adress. If so it´s clickable.

Yes, that's the correct way. Please use template override (move the change to PATH_TO_TEMPLATE/html/com_eventbooking/common/event_properties.php) so that the change won't be lost when you update to future releases of Events Booking
