Customize Components

You can customize components to change the display.

<Wrap gap="md">
  <Calendar.Root>
    <Calendar.Navigation>
      <Calendar.Control justifyContent="flex-start" px="3">
        {({ month }) =>
          `${month.getFullYear()}/${(month.getMonth() + 1).toString().padStart(2, "0")}`
        }
      </Calendar.Control>
      <Calendar.PrevButton gridColumn="6 / 7" />
      <Calendar.NextButton gridColumn="7 / 8" />
    </Calendar.Navigation>

    <Calendar.Month />
  </Calendar.Root>

  <Calendar.Root
    day={({ value }) => (
      <Indicator
        colorScheme="blue"
        size="sm"
        disabled={value.getDate() % 4 !== 0}
        offset="-3px"
        labelProps={{ minBoxSize: "2" }}
      >
        <Text as="span">{value.getDate()}</Text>
      </Indicator>
    )}
  />
</Wrap>

Control

const [value, setValue] = useState<Date | undefined>(new Date())

return <Calendar.Root value={value} onChange={setValue} />

If you use this code, you need to add "use client" to the top of the file.
