An appointment in the Scheduler widget is displayed as a rectangle lying on the timetable of the scheduler area. The time cells it occupies correspond to its scheduled time interval.

Scheduler Appointment

The appointment displayed above uses a default template defined for the Scheduler widget. This template is based on a predefined set of fields in the widget data source, requiring you to provide the required set of fields for your widget's data source, so that widget items are displayed using a default template. The following are the fields that are used in the default item template.

  • visible
    Specifies whether or not the appointment is visible.
  • disabled
    Specifies whether or not an appointment is displayed disabled.
  • html
    Specifies the html code inserted into the appointment rectangle.
  • template
    Specifies an item template that should be used to render this appointment only.
  • text
    Specifies the subject inserted into the appointment element.
  • description

  • startDate
    Specifies the appointment's start date inserted into the appointment element.
  • endDate

View Switcher

View switcher is a scheduler element used for quick switching between different scheduler views.

You can specify which views are available within the switcher. For this purpose, use the widget's views option.

var schedulerOptions = {
    // ...
    views: ['week', 'month']

When the Scheduler is displayed on a mobile device, it uses a drop-down menu to switch views. To specify whether or not the widget uses drop-down menu instead of tabs, use the useDropDownViewSwitcher option.

var schedulerOptions = {
    // ...
    useDropDownViewSwitcher: true
