Banner Collapsible Details

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its dependencies and any missing npm packages, and installs them straight into your project.

Prefer not to use the CLI? Copy the source from the Code toggle above into src/components/blocks/banner/banner21.tsx instead.

Usage

The file also exports banner21Demo, the exact props behind the preview above. Spread it to get a working section in one line, then replace it with your own data.

import { Banner21, banner21Demo } from "@/components/blocks/banner/banner21";

export default function Page() {
  return <Banner21 {...banner21Demo} />;
}

Props

Types

type AffectedService = {
  name: string;
  status: "operational" | "degraded" | "outage";
};

Behavior notes

• The body height is animated with a grid-rows-[0fr]/[1fr] transition rather than a JavaScript height measurement, so it works for any amount of content without extra logic.
• The header is a real button element, so Enter and Space already toggle the open state and aria-expanded reflects it for assistive tech.
• The leading dot stays amber regardless of the individual service statuses; it marks that the incident banner itself is active, not the worst-case service severity.
• Each row's status pill picks its color from a status-to-style lookup, so the palette stays consistent no matter how many services are passed in.
