Is there a programatic way to prevent the display of days from the previous/next months?

[andyford]

For example, usually you see a few days from the previous month (29, 30, 31 perhaps) and a few days from the next month (1, 2, 3, 4 perhaps). I want to prevent the display and interactivity of these.

I can do something like this in CSS:

.react-datepicker__day--outside-month {
  opacity: 0;
  pointer-events: none;
}

... but I'm wondering if the options API officially supports this somehow?
