Sticky Scroll Shadow

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its button 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/navbar/navbar14.tsx instead.

Usage

The file also exports navbar14Demo, 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 { Navbar14, navbar14Demo } from "@/components/blocks/navbar/navbar14";

export default function Page() {
  return <Navbar14 {...navbar14Demo} />;
}

Behavior notes

• Real client-side behavior: a useEffect attaches a genuine `scroll` event listener and flips a useState boolean once the page has scrolled more than 10px, which swaps in a shadow and a solid border class.
• The scroll listener is attached to `headerRef.current.ownerDocument.defaultView`, not the bare `window` global, this repo's block detail pages render the live preview inside a portaled iframe, and listening on the bare `window` would attach to the wrong (parent) window and never fire for scrolling inside the iframe.
• The listener is removed in the effect's cleanup function on unmount, and it also runs once immediately on mount to set the correct initial state.
• The header itself uses `sticky top-0 z-10` positioning so it stays pinned while the rest of the page scrolls underneath it.
