Date Picker

Hey all.

After reading the man page on how to use the “Date” fields (https://contactform7.com/date-field/), I’ve run into an issue that I’m not sure if it can be done or not. (Totally useful for more than just me I’m sure).

I am trying to get two date values from the user – and the first date value is working fine.

However, for a 2nd date value request, I’d like to restrict the date range the user can choose from. Useful for a range of reasons.
For example, if the user chooses the 1st date selection of 01/01/2018, I’d like the 2nd date selection to be restricted between 07/01/2018 and 12/02/2018 – which is minimum one week from the 1st date chosen and maximum six weeks from the 1st date chosen.
Would do wonders on enforcing policy on cancellations etc.

Is this simply done using syntax that I’ve missed, or just not feasible?
Very kind regards.
