Is there a similar way to create hidden fields in the regular scheduler?
I looked in the documentation for the form for the regular scheduler, and checked out the section “Types of editors” but “hidden” is not an available editor type.
How can I create a hidden field and give it an initial value in the regular scheduler?
Would I need to do it by creating a custom editor? or is there an easier way?
Yep, there is no hidden fields. But all properties assigned to the event object will be sent back to server side, for saving or any other kind of processing. So you can have multiple custom properties withou need to define related sections in lightbox.
