  defaultValue={12}
/>

Value#

Sliders are controlled with the value and defaultValue props which must fall between the minimum and maximum values which default of 0 and 100, respectively.

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <Flex gap="size-150">
      <Slider label="Cookies to buy (Uncontrolled)" defaultValue={25} />
      <Slider
        label="Cookies to buy (Controlled)"
        value={value}
        onChange={setValue}
      />
    </Flex>
  );
}

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <Flex gap="size-150">
      <Slider
        label="Cookies to buy (Uncontrolled)"
        defaultValue={25}
      />
      <Slider
        label="Cookies to buy (Controlled)"
        value={value}
        onChange={setValue}
      />
    </Flex>
  );
}

function Example() {
  let [
    value,
    setValue
  ] = React.useState(25);
  return (
    <Flex gap="size-150">
      <Slider
        label="Cookies to buy (Uncontrolled)"
        defaultValue={25}
      />
      <Slider
        label="Cookies to buy (Controlled)"
        value={value}
        onChange={
          setValue
        }
      />
    </Flex>
  );
}

Alternatively, a different scale can be used by setting the minValue and maxValue props.

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100}
/>

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100}
/>

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100}
/>

Values are formatted as plainly by default, but this can be modified by using the formatOptions prop to specify a different format. formatOptions is compatible with the option parameter of Intl.NumberFormat and is applied based on the current locale.

<Slider
  label="Currency"
  formatOptions={{style: 'currency', currency: 'JPY'}}
  defaultValue={60}
/>

<Slider
  label="Currency"
  formatOptions={{style: 'currency', currency: 'JPY'}}
  defaultValue={60}
/>

<Slider
  label="Currency"
  formatOptions={{
    style: 'currency',
    currency: 'JPY'
  }}
  defaultValue={60}
/>

Accessibility#

Depending on the visualization being used (i.e. depending on the showValueLabel prop), a label, aria-label, or aria-labelledby prop is required.

Internationalization#

To internationalize a Slider, a localized string should be passed to the label prop, aria-label prop, or value of the associated aria-labelledby element.

For languages that are read right-to-left (e.g. Hebrew and Arabic), the layout of the slider is automatically flipped. In addition, Slider automatically uses the current locale to format the value label.

Labeling#

Value labels are shown above the Slider by default, but they can also be moved to the side or hidden as needed. The label text should be in sentence case.

<Flex direction="column" maxWidth="size-3000" gap="size-300">
  <Slider label="Cookies to buy" defaultValue={25} />
  <Slider label="Donuts to buy" labelPosition="side" defaultValue={25} />
  <Slider label="Pastries to buy" showValueLabel={false} defaultValue={25} />
</Flex>

<Flex
  direction="column"
  maxWidth="size-3000"
  gap="size-300">
  <Slider label="Cookies to buy" defaultValue={25} />
  <Slider
    label="Donuts to buy"
    labelPosition="side"
    defaultValue={25}
  />
  <Slider
    label="Pastries to buy"
    showValueLabel={false}
    defaultValue={25}
  />
</Flex>

<Flex
  direction="column"
  maxWidth="size-3000"
  gap="size-300">
  <Slider
    label="Cookies to buy"
    defaultValue={25}
  />
  <Slider
    label="Donuts to buy"
    labelPosition="side"
    defaultValue={25}
  />
  <Slider
    label="Pastries to buy"
    showValueLabel={
      false
    }
    defaultValue={25}
  />
</Flex>

The value label can be updated via the valueLabel prop in cases where showing a different scale makes sense. The valueLabel should be appropriately translated.

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <Slider
      label="Cookies to buy"
      marginBottom="size-300"
      value={value}
      onChange={setValue}
      valueLabel={`${value} of 100`}
    />
  );
}

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <Slider
      label="Cookies to buy"
      marginBottom="size-300"
      value={value}
      onChange={setValue}
      valueLabel={`${value} of 100`}
    />
  );
}

function Example() {
  let [
    value,
    setValue
  ] = React.useState(25);
  return (
    <Slider
      label="Cookies to buy"
      marginBottom="size-300"
      value={value}
      onChange={setValue}
      valueLabel={`${value} of 100`}
    />
  );
}

By default, the value label is formatted as a plain number. This can be customized using the following props.

showValueLabel: Allows you to display or hide the value label.
formatOptions: Allows you to customize the format of the value.
valueLabel: Allows you to customize the value label to any string.

<Flex direction="column" maxWidth="size-3000" gap="size-300">
  <Slider label="Cookies to buy" showValueLabel={false} defaultValue={90} />
   <Slider
    label="Donuts to buy"
    maxValue={60}
    valueLabel="54 of 60 Donuts"
    defaultValue={54}
  />
   <Slider
    label="Percent donus eaten"
    maxValue={1}
    formatOptions={{style: 'percent', minimumFractionDigits: 2}}
    defaultValue={0.8912}
  />
</Flex>
