Shadcn Navbar 3 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: Three chained switchers for organization, project and environment, each environment marked by a colored dot, beside an Upgrade button

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 sidebar rail that holds the workspace switcher and the nested navigation: use the Icon Rail Dashboard block
A design system header with centered section tabs and a version badge: use the Design System Manager block
A whole product layout with a side rail, a header and the content area together: use the App Shell blocks
A keyboard palette that lists, groups and filters results as you type: use the Command component
The account settings page a user menu opens, with team, billing and API key forms: use the Profile blocks

Agent notes

WORKSPACES, PROJECTS and ENVIRONMENTS are sample lists, and each switcher only keeps its pick in local active state
The Upgrade Button and the Documentation, API Reference, Notifications and Appearance items in NavbarStatus have no handler
Each environment dot is the color class set in ENVIRONMENTS, so give a new environment its own color
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
