This demo shows how to add additional fields to the default editor window.
Here, an additional field Event Type has been added
to the default event editor and its value is processed accordingly.
In this demo, the additional field is added to the default event editor by making use of the
popupOpen event which gets triggered before the event editor getting opened on Scheduler.
popupOpen is a client-side event that triggers before any of the popups getting opened on Scheduler.
Here, the additional field (any of the form elements) is needed to be provided with the common class
e-field, so as to handle and process those additional data into the default event object.
