In this sample, your date range selection is restricted to select minimum five days and maximum ten days.
DateRangePicker has minDays and maxDays supports to force the user to select the minimum and maximum number of days in the range. Only the values in this range will be enabled. For example, in some hotel booking website, we can book rooms that includes packages like minimum 3 days to maximum 5 days. For this scenario this feature can be used. More information on the DateRangePicker minDays/maxDays support can be found in the documentation section.
