We have added a new feature today to our rental system. We already had global dates selection, but we did not have a feature to pre-filter the product listing pages by what is available and what is not available. This new feature is now released and available for immediate download in version 1.3.
To enable it go to rentals > settings > global calendar here you will find 2 new settings:
Hide (filter out) products not available for selected dates
Show whether product is available or not for selected dates on product listing pages when global dates are selected
