Shadcn Navbar 4 Block

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A wide centered search button that Cmd or Ctrl K also opens, with a New button and a 19 entry notification feed

When to use

The top bar of a signed in product, with a breadcrumb or switchers, search, alerts, avatars or a user menu
An editor toolbar with a back or close button, the page name and its run, publish or submit action
A marketing site header with mega menu panels of linked pages and a Get Started button

When not to use

A search dialog that must show grouped, filterable result rows: use the Command component
A sidebar layout whose header carries the search and a notifications feed: use the Apps Grid Header block
A whole product layout with a side rail, a header and the content area together: use the App Shell blocks
The account settings page a user menu opens, with team, billing and API key forms: use the Profile blocks

Agent notes

NOTIFICATIONS holds 19 sample entries, and no button in NotificationsPopover has a handler, Mark all as read included
NavbarSearch opens a Dialog with only an Input bound to query, so add the result list under it
The New Button in NavbarActions has no handler
Navbar takes no props, so every label, person and option it shows is fixed in the block; lift them into props to reuse it
No button, link or menu item routes or calls an API; add an onClick or a real href where each one should go
Each page.tsx adds only demo padding or dashed placeholder boxes around Navbar, none of which belongs in your layout
