Chronoform datepicker - how to add a vacation period?

I have a date picker on my chronoforms5 reservation form. Under "edit element", I have adjusted te extra parameters as follows to show that reservations could start as per October 1 2014 and we are closed on Mundays and Tuesdays - this works fine:

data-start_date=01-10-2014
data-open_days=[3,4,5,6,0]

We now have a vacation scheduled from January 30 to February 13 and I would like to add this to the parameters so that it is not possible to pick a date during this period. Can anyone advise how I should do that?

Thank you!

Hi DriezDezign,

This feature doesn't exist, but I can add it, you will need to add all the off days in a list, if this is suitable for you then please send me a message using the "contact us" page and I will email you the file after the update is finished.

Regards,
Max
