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}
/>
HTML forms#
Slider supports the name
prop for integration with HTML forms.
<Slider
label="Opacity"
defaultValue={50}
name="opacity" />
<Slider
label="Opacity"
defaultValue={50}
name="opacity" />
<Slider
label="Opacity"
defaultValue={50}
name="opacity" />
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"

<Slider

<Slider
label="Percent donus eaten"

}}

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

<Slider

</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.

Testing#
The Slider features a draggable handle that the user can interact with to change its value. Please see the following section in the testing docs for more information on how to simulate this action in your test suite.
Please also refer to React Spectrum's test suite if you find that the above isn't sufficient when resolving issues in your own test cases.
