Thanks for your reply.
In Select ranges user can change as requires. But i want to limit the date range (no of days selection to be 30 to 35 days) from the start date. Not more than that.
Eg: In select ranges
Start date: 01.05.2016 and End Date should not allow user to enter after 01.06.2016 .
Hope now its better for you to understand and guide.
Thanks.
