Cannot select 2 values inside single calendar (range)

[krisztina-tropee]

Hi! I would like to implement 2 calendar views (side by side) for selecting start and end dates and the range between them. But the issue is that when user selects both start and end dates within the same month, then the package doesn't allow selecting 2 values, like how it is for example here on Booking.
Can we do anything about it? Or should we switch to another library?
