> Top navigation bars with responsive menus, search, and user actions for web applications.

- Type: Pro blocks (Application)
- Page: https://web.dev.reui.io/blocks/application/navbar
- Blocks: 13
- Installs with a ReUI Pro or Ultimate license; setup: https://web.dev.reui.io/docs/license-setup

## 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 whole product layout with a side rail, a header and the content area together: use the [App Shell blocks](https://web.dev.reui.io/blocks/application/app-shell.md)
- A keyboard palette that lists, groups and filters results as you type: use [Command](https://web.dev.reui.io/components/command.md) (`get_component("command")`)
- The account settings page a user menu opens, with team, billing and API key forms: use the [Profile blocks](https://web.dev.reui.io/blocks/application/profile.md)

## Agent notes

- `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
