Enables the user to select an end date that is before the start date. This option is available only when the selectable configuration is set to range.

<div id="multiViewCalendar"></div>
<script>
    $("#multiViewCalendar").kendoMultiViewCalendar({
        selectable: "range",
        allowReverse: true
    });
</script>
