Slider
Sliders allow users to quickly select a value within a range. They should be used when the upper and lower bounds to the range are invariable.

Example#
<Slider label="Cookies to buy" defaultValue={12} />
<Slider label="Cookies to buy" defaultValue={12} />
<Slider
label="Cookies to buy"
defaultValue={12}
/>
Value#
Sliders are controlled with the value
prop and uncontrolled with the defaultValue
prop. This value must fall between
the Slider's minimum and maximum values, which default to 0 and 100 respectively.
function Example() {
let [value, setValue] = React.useState(25);
return (
<Flex gap="size-150" wrap>
<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" wrap>
<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"
wrap
>
<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} />
The slider value can be formatted by using the formatOptions
prop.
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}
/>
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-5000" 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-5000"
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-5000"
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>
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.getValueLabel
: Allows you to provide a custom function to format the value label.
<Flex direction="column" maxWidth="size-3000" gap="size-300">
<Slider
label="Cookies to buy"
showValueLabel={false}
defaultValue={90} />
<Slider
label="Percent donus eaten"
maxValue={1}
step={0.001}
formatOptions={{style: 'percent', minimumFractionDigits: 1}}
defaultValue={0.891} />
<Slider
label="Donuts to buy"
maxValue={60}
getValueLabel={donuts => ` of 60 Donuts`} />
</Flex>
<Flex
direction="column"
maxWidth="size-3000"
gap="size-300"

<Slider
label="Cookies to buy"
showValueLabel={false}
defaultValue={90}

<Slider
label="Percent donus eaten"

step={0.001}
formatOptions={{

minimumFractionDigits: 1
}}
defaultValue={0.891}
/>
<Slider
label="Donuts to buy"
maxValue={60}
getValueLabel={(donuts) => ` of 60 Donuts`}
/>
</Flex>
<Flex

<Slider

<Slider
label="Percent donus eaten"

step={0.001}
formatOptions={{

minimumFractionDigits:
1
}}
defaultValue={0.891}
/>
<Slider

maxValue={60}
getValueLabel={(donuts) =>
` of 60 Donuts`}
/>
</Flex>
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.
