Prevent selection/apply of dates if any of the dates in the range are invalid

[jarodium]

I would like to ask if there is room for improvement for the date range selection.

I have a use case that I select a range, but some of the dates between the range are invalidated, by means of isInvalidDate option.

Thus, I would propose a couple two possible features regarding this issue:

1. Prevent selection ( or autoapply ) and visually make the selection red and hide the apply button.
2. Provide a boolean variable that tells developers that the range contains only valid dates. For singleCalendars this variable should be always true, because there is no range.

On the 2nd case, developers should check that particular variable if it is true or false. That way it would like save an fair amount of time checking the daterange manually.

It's open source, you're free to implement any ideas you want

I wrote this library 10 years ago and don't work on it any more, so don't expect anyone to pick up feature requests

Thanks for the suggestion.

I have a similar use for the date range picker, but a bit more advanced.

I would like to preset all vacation and weekend days as not being valid dates throughout the whole year (read from a csv file). Just before displaying the date range picker, all non valid dates should be highlighted (grayed out in customizable color).
When scrolling through the next month, the same routine should be used,, meaning that you would visually see the dates that are not allowed as valid dates.

Perhaps reading from a csv file is too slow, so I would suggest pre setting some 365 day ExclusionArray (which of course needs to be filled only once by means of the csv file).
