Measured entry

efferd-header-3

navbarminimal-flatmotion on file

A client-side React header shipped as a shadcn registry block, with sticky scroll styling, Radix navigation menus, desktop calls to action, and a portal-based mobile drawer. It relies on Tailwind and shadcn conventions, Radix UI, Lucide icons, shared Button and navigation-menu components, path aliases, a class-merging utility, a scroll hook, and bundled logo and menu-toggle components.

Verdict

A capable, responsive starting point that builds and mounts in its intended environment, but it needs a shadcn-style setup and should not ship unchanged. Fix the unnamed logo link and invalid menu-list structure, then replace the placeholder links and copy.

Use it if

  • You need a responsive product-site header with grouped desktop menus and a full-screen mobile navigation drawer.
  • Your app already follows shadcn component, Tailwind token, and path-alias conventions.
  • You are prepared to replace the placeholder destinations and product-specific navigation copy.

Skip it if

  • You need an accessible drop-in without source edits, because the logo link lacks an accessible name and one menu list has invalid direct children.
  • Your project does not use Tailwind or shadcn-style shared UI modules and you want a self-contained header.
  • You want a lightweight navigation bar without Radix menus, icon assets, scroll state, and portal behavior.

In a non-shadcn project, add Tailwind with the expected theme tokens and animation utilities, configure the at-sign source alias, install Radix UI and Lucide React, and supply compatible Button and navigation-menu modules plus the class-merging utility, scroll hook, logo, and menu-toggle icon. Preserve client rendering and portal support.
