The schedule component provides many options already, but it does not offer the full suite of options supported by the underlying FullCalendar library. This is an advanced option that lets you configure the schedule to your your needs. Use the extender option and provide a custom JavaScript function. That function is called before the schedule is initialized. Within that function, you can use the this keyword to access the current schedule widget and modify the this.cfg options passed to FullCalendar. See the FullCalendar documentation for more details and all available options.
