Multiple

ESM migration: keep the existing options and callbacks, import months from vanilla-calendar-pro, and add it to the constructor’s extensions: [months] array without calling it.

The 'multiple' calendar type displays multiple months, allowing you to select days in each of them. This type of calendar is useful when the user needs to select multiple dates across different months. To do this, you need to use the selectionDatesMode parameter and set its value to 'multiple'.

Example code for creating a calendar with the 'multiple' type:

If you need to select date ranges, you can use the selectionDatesMode parameter and set its value to 'multiple-ranged'. This allows you to select date ranges instead of individual days.
