Calendar:about disabled logic

[kl-nevermore]

Describe the bug

The calendar only supports disabledDates and disabledDays

But year and month have attributes data-p-disabled, this value never changed by props.disabledDates or props.disabledDays

monthPickerValues data-p-disabled always true

https://github.com/primefaces/primereact/blob/master/components/lib/calendar/Calendar.js#L3654

yearPickerValues data-p-disabled always false

https://github.com/primefaces/primereact/blob/master/components/lib/calendar/Calendar.js#L3697

is this an issue or a feature? if it will be fixed, Is it a good choice to accept a new prop like example

disabledDate?: (year: number, month: number, day: number) => boolean;

<Calendar
    value={date}
    onChange={(e) => setDate(e.value)}
    disabledDate={(y, m, d) => {
        return y > 1999 && m > 1;
    }}
/>

@melloware
Now the disabling logic of the three panels has no correlation

Do you think this logic is as expected?

• If any date can be selected in currentYear or currentMonth, then the year and month should also be selectable
• If any month can be selected, then the year should also be selectable
• if all date disabled ,then the year and month should also be disabled
• if all month disabled ,then the year and date should also be disabled
• if all year disabled ,then the mouth and date should also be disabled

This is tricky because now you have to check the disabledDates and compare each month and or year to see if it encompasses the entire disabled Dates right? For example if disabled Dates had every date in March except March 15 then March should be active but if it also had March 15 then the month of March would be disabled?

yes

what I thought was when I passed on the new props，the disabledDates and disabledDays will be ignored

If it's like what you said, then need to combine the logic

when changed year picker, will be checking all the days, there may be some performance issues, but I think it's okay. only 3000+ times

I will test it under slow 4x and 6x and compare it with the current situation
