Examples

App update notification

The registry item's complete usage pattern with a controlled banner, update CTA, and reopen button.

app-update-notification.tsx
"use client";import { Info } from "lucide-react";import * as React from "react";import {  Banner,  BannerActions,  BannerClose,  BannerContent,  BannerDescription,  BannerIcon,  BannerTitle,} from "@/registry/bases/radix/ui/banner";import { Button } from "@/registry/bases/radix/ui/button";export default function UpdateBanner() {  const [open, setOpen] = React.useState(true);  return (    <>      <Banner open={open} onOpenChange={setOpen}>        <BannerIcon>          <Info />        </BannerIcon>        <BannerContent>          <BannerTitle>New update available</BannerTitle>          <BannerDescription>            A new version of the app is available. Update now to get the latest            features.          </BannerDescription>        </BannerContent>        <BannerActions>          <Button size="sm">Update now</Button>          <BannerClose />        </BannerActions>      </Banner>      {!open && <Button onClick={() => setOpen(true)}>Show banner</Button>}    </>  );}

Maintenance notice

A dismissible banner for planned maintenance with a CTA to view details.

maintenance-notice.tsx
"use client";import { Info } from "lucide-react";import * as React from "react";import {  Banner,  BannerActions,  BannerClose,  BannerContent,  BannerDescription,  BannerIcon,  BannerTitle,} from "@/registry/bases/radix/ui/banner";import { Button } from "@/registry/bases/radix/ui/button";export default function MaintenanceBanner() {  const [open, setOpen] = React.useState(true);  return (    <Banner open={open} onOpenChange={setOpen}>      <BannerIcon>        <Info />      </BannerIcon>      <BannerContent>        <BannerTitle>Scheduled maintenance</BannerTitle>        <BannerDescription>          Some features may be unavailable tonight from 10:00 PM to 11:00 PM.        </BannerDescription>      </BannerContent>      <BannerActions>        <Button size="sm">View details</Button>        <BannerClose />      </BannerActions>    </Banner>  );}

Feature announcement

A persistent feature announcement using the same composable banner structure.

feature-announcement.tsx
"use client";import { Info } from "lucide-react";import * as React from "react";import {  Banner,  BannerActions,  BannerClose,  BannerContent,  BannerDescription,  BannerIcon,  BannerTitle,} from "@/registry/bases/radix/ui/banner";import { Button } from "@/registry/bases/radix/ui/button";export default function FeatureBanner() {  const [open, setOpen] = React.useState(true);  return (    <Banner open={open} onOpenChange={setOpen}>      <BannerIcon>        <Info />      </BannerIcon>      <BannerContent>        <BannerTitle>Introducing team workspaces</BannerTitle>        <BannerDescription>          Organize projects, members, and permissions in one shared workspace.        </BannerDescription>      </BannerContent>      <BannerActions>        <Button size="sm">Learn more</Button>        <BannerClose />      </BannerActions>    </Banner>  );}

Accessibility

  • The example uses a controlled open state and passes onOpenChange, allowing the banner to be dismissed and reopened without losing synchronization.
  • The primary action has visible text, making its purpose clear to assistive technology users.
  • BannerClose supplies the dismiss control through the imported Banner component; keep it available when users need to hide the notice.
  • The Info icon is presented without an explicit accessible label in the demo, so it should remain supplementary to the visible title and description rather than carrying essential meaning.
  • Keep banner copy concise and ensure the CTA remains understandable from its visible label.
