Add support for multiple days/range selections

[victorpinheiro]

Is it possible to set multiple days or multiple ranges as default selection?
Couldn't find anything about this on documentation

[GiovanniFrigo]

As for the current design, only one date or range are supported in the selection by the user, so the same applies to the default selection.

I may consider adding the support for it in the future!

@victorpinheiro @GiovanniFrigo We can use customClasses with state to select multiple dates.
const [ dates, setDates ] = useState([]);

<Calendar
  year={2021}
  onPickDate={ date => setDates([ ...dates, date.format('MM/DD/YYYY') ]) }
  customClasses={{
    selected: day => dates.includes(day.format('MM/DD/YYYY'))
  }}
/>
