toggles the ability to add events to calendars
webix.ui({
view: "scheduler",
date: new Date(2020, 4, 21, 0, 0, 0),
url: "https://docs.webix.com/calendar-backend/",
calendars: false // disables the ability to work with calendars
});
If it is set to false users cannot work with calendars i.e. add events to them or change calendars in the event edit form.
