I have KeyboardDatePicker from materialUI and i have a format={'yyyy.MM.dd'}, and its work fine. But when i put only year or year and month it shows me 'Invalid date' error. It is possible to have options when I have only year it will accept it, or year and month? Maybe somthing like dunamic format ? Beacuse when I change to yyyy or yyyy.mm it works also fine.

<KeyboardDatePicker
    id='date-picker-dialog'
    format={ 'yyyy.MM.dd' }
    KeyboardButtonProps={ { "aria-label": "change date" } }
    minDate={ new Date('0001-01-01') }
/>
