Import

import '@videojs/html/ui/quality-radio-group';
import '@videojs/html/ui/menu-radio-item';
import '@videojs/html/ui/menu-item-indicator';

Anatomy

<media-quality-radio-group>
  <template>
    <media-menu-radio-item>
      <span data-part="label"></span>
      <span data-part="tier"></span>
      <span data-part="badge"></span>
      <media-menu-item-indicator></media-menu-item-indicator>
    </media-menu-radio-item>
  </template>
</media-quality-radio-group>

Behavior

The group is available when the configured media exposes more than one video rendition. The first generated option is Auto; selecting it returns control to adaptive bitrate selection. Pass formatRendition to customize visible rendition labels.

<media-quality-radio-group> generates <media-menu-radio-item> children. Add an optional <template> with a single <media-menu-radio-item> to customize each generated item.

Styling

Attribute	Values	Description
`data-quality`	`string`	Current quality value.
`data-disabled`	Present / absent	Present when quality selection is disabled.
`data-hidden`	Present / absent	Present when multiple renditions are unavailable.
`data-availability`	`"available"` / `"unavailable"`	Whether multiple renditions are available.

Unavailable groups receive the native hidden attribute.

Accessibility

The group uses the menu radio group pattern.

The element receives an accessible label from the label property or defaults to Quality.

API Reference

media-quality-radio-group

Menu radio group that generates an Auto <media-menu-radio-item> plus one per video rendition, and shares the selected label and availability with an enclosing menu.
