Begränsa val

Använd callback isDateUnavailable för att markera datum som inte valbara. Använd minValue till exempel för att begränsa datum före dagens datum.

import { today, getLocalTimeZone } from '@internationalized/date'

export const UnavailableDateExample = () => {
  const now = today(getLocalTimeZone())
  const isDateUnavailable = (date: DateValue) => {
    return date.compare(now.add({ weeks: 1 })) < 0
  }

  return (
    <DatePicker
      label='Välj ett datum'
      description='Fast inte förrän om en vecka'
      isDateUnavailable={isDateUnavailable}
      minValue={now}
    />
  )
}
