How can I select all dates column in date picker?

[youngseagul]

I am using this multi date-picker.

There are fowling columns headers in date-picker,

Sun Mon Tue Wed Thu Fri Sat

I want to select all days under column header if any of the above column header got a click from user.

Example : if user clicks on “Mon”, I want to select all Mondays of the month.

Any help would be much appreciated

actually this is not an issue, i just need help
