Value#
In addition to a string as shown above, a LabeledValue
accepts numbers, dates, times, and lists of strings in the value
prop.
Numbers#
When the value
prop is set to a number, LabeledValue
formats it according to the user's locale.
<LabeledValue label="Number of cookies" value={1024} />
<LabeledValue label="Number of cookies" value={1024} />
<LabeledValue
label="Number of cookies"
value={1024}
/>
Custom formatOptions
can also be provided to format the value as a percentage, unit, currency, etc. This prop is compatible
with the option parameter of Intl.NumberFormat.
<LabeledValue
label="File size"
value={1.2}
formatOptions={{ style: 'unit', unit: 'megabyte' }}
/>
<LabeledValue
label="File size"
value={1.2}
formatOptions={{ style: 'unit', unit: 'megabyte' }}
/>
<LabeledValue
label="File size"
value={1.2}
formatOptions={{
style: 'unit',
unit: 'megabyte'
}}
/>
An object with start
and end
properties may also be provided to format a numeric range.
<LabeledValue
label="Price range"
value={{ start: 150, end: 400 }}
formatOptions={{
style: 'currency',
currency: 'USD',
minimumFractionDigits: 0
}}
/>
<LabeledValue
label="Price range"
value={{ start: 150, end: 400 }}
formatOptions={{
style: 'currency',
currency: 'USD',
minimumFractionDigits: 0
}}
/>
<LabeledValue
label="Price range"
value={{
start: 150,
end: 400
}}
formatOptions={{
style: 'currency',
currency: 'USD',
minimumFractionDigits:
0
}}
/>
Dates and times#
The value
prop may be set to a JavaScript Date object, or one of the types from @internationalized/date to display a date or time, which is formatted according to the user's locale.
import {getLocalTimeZone, today} from '@internationalized/date';
<LabeledValue
label="Date modified"
value={today(getLocalTimeZone()).subtract({ weeks: 1 })}
/>
import {
getLocalTimeZone,
today
} from '@internationalized/date';
<LabeledValue
label="Date modified"
value={today(getLocalTimeZone()).subtract({ weeks: 1 })}
/>
import {
getLocalTimeZone,
today
} from '@internationalized/date';
<LabeledValue
label="Date modified"
value={today(
getLocalTimeZone()
).subtract({
weeks: 1
})}
/>
By default, the formatting depends on the type of value provided. Above, a CalendarDate is provided, so only the date is displayed. To display a time, pass a Time object. You can also provide a CalendarDateTime or ZonedDateTime to display a date with a time.
import {getLocalTimeZone, now} from '@internationalized/date';
<LabeledValue label="Page load time" value={now(getLocalTimeZone())} />
import {
getLocalTimeZone,
now
} from '@internationalized/date';
<LabeledValue
label="Page load time"
value={now(getLocalTimeZone())}
/>
import {
getLocalTimeZone,
now
} from '@internationalized/date';
<LabeledValue
label="Page load time"
value={now(
getLocalTimeZone()
)}
/>
An object with start
and end
properties may also be provided to format a date or time range.
import {Time} from '@internationalized/date';
<LabeledValue
label="Business hours"
value={{ start: new Time(8, 30), end: new Time(18) }}
/>
import {Time} from '@internationalized/date';
<LabeledValue
label="Business hours"
value={{ start: new Time(8, 30), end: new Time(18) }}
/>
import {Time} from '@internationalized/date';
<LabeledValue
label="Business hours"
value={{
start: new Time(
8,
30
),
end: new Time(18)
}}
/>
Custom formatOptions
can also be provided control the exact date format. This prop is compatible
with the option parameter of Intl.DateTimeFormat.
<LabeledValue
label="Appointment date"
value={new Date(2022, 6, 5)}
formatOptions={{ dateStyle: 'short' }}
/>
<LabeledValue
label="Appointment date"
value={new Date(2022, 6, 5)}
formatOptions={{ dateStyle: 'short' }}
/>
<LabeledValue
label="Appointment date"
value={new Date(
2022,
6,
5
)}
formatOptions={{
dateStyle: 'short'
}}
/>
Lists#
When the value
prop is set to an array of strings, they are rendered as a comma-separated list according to the user's locale.
<LabeledValue
label="Pizza toppings"
value={['Pepperoni', 'Pineapple', 'Mushroom', 'Garlic']}
/>
<LabeledValue
label="Pizza toppings"
value={['Pepperoni', 'Pineapple', 'Mushroom', 'Garlic']}
/>
<LabeledValue
label="Pizza toppings"
value={[
'Pepperoni',
'Pineapple',
'Mushroom',
'Garlic'
]}
/>
By default, the list is displayed as a conjunction (an "and"-based grouping of items). This may be changed to a disjunction (an "or"-based grouping), or a pure comma-separated list using the formatOptions
prop. This is compatible with the option parameter of Intl.ListFormat.
<LabeledValue
label="Interests"
value={['Travel', 'Hiking', 'Snorkeling', 'Camping']}
formatOptions={{ type: 'unit' }}
/>
<LabeledValue
label="Interests"
value={['Travel', 'Hiking', 'Snorkeling', 'Camping']}
formatOptions={{ type: 'unit' }}
/>
<LabeledValue
label="Interests"
value={[
'Travel',
'Hiking',
'Snorkeling',
'Camping'
]}
formatOptions={{
type: 'unit'
}}
/>
Labeling#
A visual label must be provided to the LabeledValue
using the label
prop.
Internationalization#
In order to internationalize a LabeledValue
, a localized string should be passed to the label
prop.
LabeledValue
automatically formats numbers, dates, times, and lists according to the user's locale, as defined by the Provider component. String values provided to a LabeledValue
should be translated accordingly.

Visual options#
Label alignment and position#
By default, the label is positioned above the LabeledValue
. The labelPosition
prop can be used to position the label to the side. The labelAlign
prop can be used to align the label as "start" or "end". For left-to-right (LTR) languages, "start" refers to the left most edge of the LabeledValue
and "end" refers to the right-most edge. For right-to-left (RTL) languages, this is flipped.
<LabeledValue
label="File name"
value="Onboarding.pdf"
labelPosition="side"
labelAlign="end"
/>
<LabeledValue
label="File name"
value="Onboarding.pdf"
labelPosition="side"
labelAlign="end"
/>
<LabeledValue
label="File name"
value="Onboarding.pdf"
labelPosition="side"
labelAlign="end"
/>

A ContextualHelp element may be placed next to the label to provide additional information or help about a LabeledValue.
