I need a new Field-Type for Gravity-Forms, called Data-Range.
This field-type should have two data-(picker)-fields. Start-Date and End-Date (like from every travel booking form)
This field-type should work as all of the other field-types from gravity forms with all the default features (e.g. admin-only, css, …)
It must be possibel to define a min-range of days and a max-range of days.
Example :
If the min-range of days is set to 7 and the max-range is set to 21.
Start date : 1st …
