RadioGroup Radio buttons allow users to select a single option from a list of mutually exclusive options.
All possible options are exposed up front for users to compare.
< RadioGroup label = "Favorite pet" >
< Radio value = "dogs" > Dogs< / Radio >
< Radio value = "cats" > Cats< / Radio >
< / RadioGroup >
< RadioGroup label = "Favorite pet" >
< Radio value = "dogs" > Dogs< / Radio >
< Radio value = "cats" > Cats< / Radio >
< / RadioGroup >
< RadioGroup label = "Favorite pet" >
< Radio value = "dogs" >
Dogs
< / Radio >
< Radio value = "cats" >
Cats
< / Radio >
< / RadioGroup >
RadioGroup accepts multiple Radio elements as children.
Each Radio represents an option that can be selected, labeled by its children.
Note: A Radio cannot be used outside of a RadioGroup.
RadioGroup only allows single selection. An initial, uncontrolled value can be provided to the RadioGroup using the defaultValue
prop.
Alternatively, a controlled value can be provided using the value
prop.
function Example ( ) {
let [ selected, setSelected] = React . useState ( 'yes' ) ;
return (
< Flex gap = "size-300" >
< RadioGroup label = "Are you a wizard? (uncontrolled)" defaultValue = "yes" >
< Radio value = "yes" > Yes< / Radio >
< Radio value = "no" > No< / Radio >

) ;
}
A visual label should be provided for the RadioGroup using the label
prop. If the RadioGroup is required, the isRequired
and
necessityIndicator
props can be used to show a required state.

< RadioGroup label = "Favorite avatar" >

If a visible label isn't specified for a RadioGroup, an aria-label
must be provided for accessibility. If the field is labeled by a separate element, an aria-labelledby
prop must be provided using the id of the labeling element instead.
Radio elements should always have a visible label.
To internationalize a RadioGroup, a localized string should be set as the child content of the Radio.
For languages that are read right-to-left (e.g. Hebrew and Arabic), the Radio is automatically placed on the right side of the text. When the necessityIndicator prop is set to "label", a localized string will be provided for "(required)" or "(optional)" automatically.
RadioGroup accepts an onChange
prop, which is triggered when a user changes the selected value.
The example below uses onChange
to log how the user is interacting with the component.
function Example ( ) {
let [ selected, setSelected] = React . useState ( '' ) ;
return (
< >
< RadioGroup label = "Favorite avatar" onChange = { setSelected} >
< Radio value = "wizard" > Wizard< / Radio >
< Radio value = "dragon" > Dragon< / Radio >
< / RadioGroup >
< div > You have selected: { selected} < / div >
< / >
) ;
}
function Example ( ) {
let [ selected, setSelected] = React . useState ( '' ) ;
return (
< >
< RadioGroup
label = "Favorite avatar"
onChange = { setSelected} >
< Radio value = "wizard" > Wizard< / Radio >
< Radio value = "dragon" > Dragon< / Radio >
< / RadioGroup >
< div > You have selected: { selected} < / div >
< / >
) ;
}
function Example ( ) {
let [
selected,
setSelected
] = React . useState ( '' ) ;
return (
< >
< RadioGroup
label = "Favorite avatar"
onChange = {
setSelected
} >
< Radio value = "wizard" >

< Radio value = "dragon" >
Dragon
< / Radio >
< / RadioGroup >
< div >
You have
selected:{ ' ' }
{ selected}
< / div >
< / >
) ;
}
RadioGroups can display a validation state to communicate to the user if the current value is invalid.
Implement your own validation logic in your app and pass "invalid"
to the RadioGroup via the validationState
prop.
< RadioGroup label = "Favorite avatar" validationState = "invalid" >
< Radio value = "wizard" > Wizard< / Radio >
< Radio value = "dragon" > Dragon< / Radio >
< / RadioGroup >
< RadioGroup
label = "Favorite avatar"
validationState = "invalid" >
< Radio value = "wizard" > Wizard< / Radio >
< Radio value = "dragon" > Dragon< / Radio >

< RadioGroup

RadioGroups are vertically oriented by default.
The orientation
prop can be used to change the orientation to horizontal.
< RadioGroup label = "Favorite avatar" orientation = "horizontal" >
< Radio value = "wizard" > Wizard< / Radio >
< Radio value = "dragon" > Dragon< / Radio >
< / RadioGroup >

< Radio value = "dragon" >
Dragon

< / RadioGroup >
Label position and alignment# View guidelines
By default, the label is positioned above the RadioGroup.
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 RadioGroup
and "end" refers to the right most edge. For right-to-left (RTL) languages, this is flipped.

The isReadOnly prop makes the selection immutable. Unlike isDisabled, the RadioGroup remains focusable.
