## Best for

An org and repo path with a branch menu listing 4 branches, the default marked, plus Remix and Vite targets and a Run button

## Agent notes

- Picking a `BRANCHES` item changes nothing, because the trigger always prints the fixed `REPO` branch
- Share, Run, Deploy with Remix and Vite project have no handler in `NavbarActions`
- `NavbarBrand` hardcodes the CodeLive name and the org `BreadcrumbLink` links to a placeholder `href`; replace both

## When not to use

- A sidebar layout whose header carries org, application and environment dropdowns: use [Environment Switcher](https://web.dev.reui.io/blocks/application/app-shell/app-shell-7.md) (`get_block("app-shell-7")`)
- A workspace bar with presence avatars beside filter and sort menus: use [Team Presence](https://web.dev.reui.io/blocks/application/navbar/navbar-2.md) (`get_block("navbar-2")`)

## Install

```bash
npx shadcn@latest add @reui/navbar-9
```

## About Navbar blocks

### 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
