I'm working on a calendar view that will allow user to make a reservation for a specific day and time. My problem is current behaviour of selectAllow function. I want to restrict the user to be able to select max 2 slots (60 minutes in that example), and if he selects more, the selection should stay at the maximum possible time range, instead of disappearing and showing the not-allowed cursor. Would that be possible?

A fiddle for better visualization:

Try to select more than 2 slots in a single day.
