For the reservation time options, could we have something like this where a user sees at once all the time options and then click on one to select their reservation time? (like in Appointment Booking) - Monosnap
The most important is I also need the opportunity to block some specific time for booking for each day.
Hi there, @Piam_Mansouri 
Thanks for the suggestion! We’ll keep it in mind and see if it gains traction with others 
Add the ability to automatically hide or block fields once they have been selected.
Hi there, @user13383
We already have this idea on the Wishlist, and I’ve merged your comment with it. We’ll keep you posted here
