Only show calender without any fields

Hello.
Yes, it’s possible.

You need to insert the shortcode only for availability calendar, instead of shortcode for booking form with calendar.

So please open your page for editing, remove exist shortcode like this:

[booking type=1]

and insert shortcode like this:

[bookingcalendar type=1]

Save changes. Test it.

Kind Regards.

Thanks! And last one: how can I add the avaible (green) and unavaible (red) by myself? Instead of people booking.

Hello.
You can do this at the admin panel at Booking > Add booking page.
