Current calendar open status.
Sets the calendar open status.
Toggles the calendar open status. If no parameters are passed, the calendar will simply toggle its open status. If the isOpen parameter is passed, that will set the calendar open status to the value of the isOpen parameter. If the eventKey parameter is set to 'Escape', that will invoke the date pickers onEscapePress event to toggle the correct control appropriately.
Allows finer control over the calendar's open state when a React ref is passed into the date picker component. Accessed via ref.current[property], e.g. ref.current.toggleCalendar().
