Usage

usage.tsx
import { Banner, BannerActions, BannerClose, BannerContent, BannerDescription, BannerTitle, Banners } from "@/components/ui/banner";export function Example() {  return (    <Banners side="top" strategy="fixed" maxVisible={2}>      <main>Page content</main>      <Banner variant="info" priority={1} duration={5000}>        <BannerContent>          <BannerTitle>Scheduled maintenance</BannerTitle>          <BannerDescription>Some features may be briefly unavailable tonight.</BannerDescription>        </BannerContent>        <BannerActions>          <BannerClose aria-label="Dismiss maintenance notice" />        </BannerActions>      </Banner>    </Banners>  );}
  • Use for important site-wide announcements, status messages, maintenance notices, or contextual alerts.
  • Use Banners when multiple notifications need priority ordering, queuing, automatic dismissal, or fixed/sticky positioning.
  • Use the standalone Banner when a message should render directly in the surrounding layout.
  • Combine BannerIcon, BannerContent, BannerTitle, BannerDescription, BannerActions, and BannerClose for consistent structure and controls.

Examples

Informational announcement

A dismissible informational banner with a title, description, and close action.

informational-announcement.tsx
import { Banner, BannerClose, BannerContent, BannerDescription, BannerTitle } from "@/components/ui/banner";export function Announcement() {  return (    <Banner variant="info">      <BannerContent>        <BannerTitle>New dashboard available</BannerTitle>        <BannerDescription>Try the updated analytics experience.</BannerDescription>      </BannerContent>      <BannerClose aria-label="Dismiss announcement" />    </Banner>  );}

Queued banners with priority

A managed stack that displays high-priority messages first and automatically removes them after a duration.

queued-banners-with-priority.tsx
import { Banner, BannerActions, BannerClose, BannerContent, BannerDescription, BannerTitle, Banners } from "@/components/ui/banner";export function NotificationQueue() {  return (    <Banners maxVisible={2} side="bottom" strategy="fixed">      <Banner variant="success" priority={2} duration={4000}>        <BannerContent>          <BannerTitle>Payment complete</BannerTitle>          <BannerDescription>Your order is being prepared.</BannerDescription>        </BannerContent>        <BannerActions><BannerClose aria-label="Dismiss payment message" /></BannerActions>      </Banner>      <Banner variant="warning" priority={1}>        <BannerContent>          <BannerTitle>Profile incomplete</BannerTitle>          <BannerDescription>Add a phone number to improve account recovery.</BannerDescription>        </BannerContent>        <BannerActions><BannerClose aria-label="Dismiss profile message" /></BannerActions>      </Banner>    </Banners>  );}

Non-dismissible destructive banner

A destructive message that remains visible because its close control is disabled.

non-dismissible-destructive-banner.tsx
import { Banner, BannerClose, BannerContent, BannerDescription, BannerTitle } from "@/components/ui/banner";export function ServiceError() {  return (    <Banner variant="destructive" dismissible={false}>      <BannerContent>        <BannerTitle>Service unavailable</BannerTitle>        <BannerDescription>We are working to restore access.</BannerDescription>      </BannerContent>      <BannerClose aria-label="Dismiss service message" />    </Banner>  );}

API reference

PropTypeDefaultDescription
Banners.childrenReact.ReactNodeundefinedContent rendered around the managed banner container. For static or sticky strategies, the banner container is rendered before or after this content according to side.
Banners.maxVisiblenumber1Maximum number of queued banners rendered at once. Banners are ordered by descending priority, with equal priorities retaining insertion order.
Banners.side"top" | "bottom""top"Edge from which banners enter and at which the banner container is positioned.
Banners.strategy"fixed" | "static" | "sticky" | "absolute""fixed"CSS positioning strategy for the banner container. Fixed and absolute strategies render the container through a portal; static and sticky strategies render it in the component layout.
Banners.containerElement | DocumentFragment | nulldocument.body for fixed/absolute strategiesPortal target for fixed or absolute banner containers. It is ignored for static and sticky strategies.
Banner.childrenReact.ReactNodeundefinedBanner content. When rendered inside Banners, this content is registered with the manager and rendered in the managed container.
Banner.variant"default" | "info" | "success" | "warning" | "destructive""default"Visual color variant.
Banner.openbooleanundefinedControlled open state. When provided, the banner is controlled and closing calls onOpenChange without changing internal state.
Banner.defaultOpenbooleantrueInitial open state for an uncontrolled banner.
Banner.onOpenChange(open: boolean) => voidundefinedCalled when the banner is closed, including when a managed banner is dismissed.
Banner.onDismiss() => voidundefinedCalled when a managed banner is removed after its close animation or when it is removed during cleanup.
Banner.prioritynumber0Ordering priority in Banners. Higher values appear before lower values.
Banner.durationnumberundefinedTime in milliseconds before the banner begins its removal animation. Values greater than zero enable automatic dismissal.
Banner.dismissiblebooleantrueControls whether BannerClose is enabled by default.
Banner.asChildbooleanfalseUses Radix Slot to render the root banner element as its child element instead of a div.
Banner classNamestringundefinedAdditional classes merged with the variant classes.
Banner div propsReact.ComponentProps<"div">undefinedAll standard div attributes are accepted and forwarded to the standalone root, including id, style, data attributes, and event handlers. In managed mode, the root is not rendered.
BannerIconDivPropsundefinedAccepts standard div props plus asChild. Renders the icon region with shrink prevention and a default size for direct SVG children.
BannerContentDivPropsundefinedAccepts standard div props plus asChild. Renders the flexible content column.
BannerTitleReact.ComponentProps<"div">undefinedAccepts standard div props and renders the title region.
BannerDescriptionReact.ComponentProps<"div">undefinedAccepts standard div props and renders the description region.
BannerActionsDivPropsundefinedAccepts standard div props plus asChild. Renders the horizontal actions region.
BannerCloseReact.ComponentProps<typeof Button>undefinedAccepts all props supported by the imported Button component. The default control is a ghost icon-sm button. Its disabled state defaults to the inverse of dismissible; a click first invokes the supplied onClick and closes the banner unless the event is prevented or the control is disabled.

Accessibility

  • Managed and standalone banners render with role="status" and aria-live="polite", so updates are announced without being treated as urgent interruptions.
  • Provide an accessible name for BannerClose with aria-label when the close icon is the only content.
  • BannerClose is disabled automatically when dismissible is false, and an explicitly supplied disabled prop takes precedence.
  • The close handler respects event.preventDefault(), allowing application code to prevent dismissal.
  • When using asChild, ensure the slotted element remains an appropriate status container and preserves keyboard and focus behavior.
  • Use concise titles and descriptions because queued banners may be announced and displayed simultaneously.
