This property accepts one of the following values. To see how they affect the appointments, switch between Scheduler views.

  • "auto"
    Appointments are narrowed down to a predefined size value that depends on the view type. Appointments that do not fit into the cell are hidden, and the cell displays an overflow indicator. Users can click the indicator to display the hidden appointments in a tooltip.

  • "unlimited"
    Appointments are narrowed down without a limit to be fit into a cell.

  • Number
    The number specifies the maximum number of appointments allowed in a single cell. Appointments that exceed this number are hidden, and the cell displays an overflow indicator. Users can click the indicator to display the hidden appointments in a tooltip.
