It would be great if it is possible to disable certain dates in the calendar. Maybe if it is possible to pass an entire array with calendar-date-objects, it would be more convenient to disable dates or highlight certain dates. e.g. CalendarDateObject could have 3 properties: - CSS class (this style would be applied to that certain date) - Disabled true/false; default = true (if disabled, date is not clickable) - Footer text (When you hover over the date, you can see this text in the footer) By using an array of objects, you don't have to check if a date is in a certain array to change the CSS-class of that date. In the way it is now implemented, you have to write all lines of code to check if the date is in an array.
