Radio Group
A group of radio controls for choosing exactly one value.
@data-slot/radio-groupSource ↗bun add @data-slot/radio-groupnpm install @data-slot/radio-grouppnpm add @data-slot/radio-groupAnatomy
Each item needs a data-value. Add data-name to the root and the controller generates hidden native radios that share that field name, so the group submits and resets with the form.

Initialization
create(scope?)
Find and bind uninitialized [data-slot="radio-group"] descendants of scope (defaults to document). Returns RadioGroupController[] for newly bound roots. To initialize the scope element itself, use createRadioGroup.
import { create } from "@data-slot/radio-group";
const controllers = create();
createRadioGroup(root, options?)
Create a RadioGroupController for one root element. JavaScript options take precedence over the corresponding data attributes. Calling this again for a bound root returns its existing controller; destroy it before rebinding with new options.
import { createRadioGroup } from "@data-slot/radio-group";
const controller = createRadioGroup(element, {});
Slots
Runtime Slots
radio-group- Root element that manages the selected value, radio-group semantics, and keyboard navigation.radio-group-item- Individual radio control identified bydata-value; receives checked state and participates in roving focus.radio-group-indicator- Optional visual indicator inside an item; receives checked and disabled state for styling.
Options
Options can be passed via JavaScript or data attributes (JS takes precedence).
| Option | Data Attribute | Type | Default | Description |
|---|---|---|---|---|
defaultValue |
data-default-value |
string |
null |
Initially selected value |
name |
data-name |
string |
- | Shared form field name for generated radios |
disabled |
data-disabled |
boolean |
false |
Disable user interaction and submission |
readOnly |
data-read-only / data-readOnly |
boolean |
false |
Prevent user interaction while keeping programmatic control |
required |
data-required |
boolean |
false |
Require a selected value for native validation |
onValueChange |
- | (value: string | null) => void |
- | Callback fired when selection changes |
Controller
interface RadioGroupController {
readonly value: string | null;
select(value: string): void;
clear(): void;
destroy(): void;
}
Events
Outbound Events
Listen for these events on the root element.
| Event | Detail | Description |
|---|---|---|
radio-group:change |
{ value: string | null } |
Fires when the selected value changes |
Inbound Events
Dispatch these events on the root element.
| Event | Detail | Description |
|---|---|---|
radio-group:set |
{ value: string | null } |
Select or clear a value programmatically |
// Listen for changes
root.addEventListener("radio-group:change", (e) => {
console.log("Value:", e.detail.value);
});
// Set value from outside
root.dispatchEvent(
new CustomEvent("radio-group:set", {
detail: { value: "pro" },
}),
);
// Clear selection from outside
root.dispatchEvent(
new CustomEvent("radio-group:set", {
detail: { value: null },
}),
);
Note: Inbound events are blocked when the group is disabled or read-only. Controller methods still work.
Styling
The controller mirrors Base/shadcn-style presence attributes onto items and indicators:
[data-slot="radio-group-item"][data-checked] { ... }
[data-slot="radio-group-item"][data-unchecked] { ... }
[data-slot="radio-group-item"][data-disabled] { ... }
[data-slot="radio-group-indicator"][data-checked] { ... }
[data-slot="radio-group-indicator"][data-unchecked] { ... }
The root also mirrors the current value:
[data-slot="radio-group"][data-value="pro"] { ... }
Keyboard Navigation
| Key | Action |
|---|---|
ArrowRight / ArrowDown |
Move to the next enabled item and select it |
ArrowLeft / ArrowUp |
Move to the previous enabled item and select it |
Home |
Select the first enabled item |
End |
Select the last enabled item |
Space / Enter |
Select the focused item |
Accessibility
- Root gets
role="radiogroup"plusaria-disabled,aria-readonly, andaria-required - Items get
role="radio",aria-checked,aria-disabled, and rovingtabindex - Disabled items are skipped during keyboard navigation
- Wrapping labels and
label[for]associations are mirrored toaria-labelledby
Labeling Patterns
Wrapping Labels
<label>
<span data-slot="radio-group-item" data-value="starter">
<span data-slot="radio-group-indicator"></span>
</span>
Starter
</label>
Sibling label[for]
<label for="plan-pro">Pro</label>
<span id="plan-pro" data-slot="radio-group-item" data-value="pro">
<span data-slot="radio-group-indicator"></span>
</span>
Form Integration
The controller generates one visually hidden native radio input per item. When name is provided, those inputs share the same field name and participate in native form submission and reset behavior.
<form>
<div data-slot="radio-group" data-name="plan" data-required>
<label>

Starter
