Measured entry

shadcn-block-sidebar-14

sidebarminimal-flat

A shadcn registry block for a right-side, documentation-style table of contents. It ships as a page plus an AppSidebar component, with breadcrumb and sidebar registry dependencies. It assumes React, Tailwind utility classes, the @ alias, and shadcn primitives backed by Radix UI, class-variance-authority, and Lucide.

Verdict

A practical fit for documentation-style dashboards, but it needs a shadcn-style setup because the bare project cannot resolve the shared utility module. Replace the sample links and reconcile the page's main landmarks before shipping.

Use it if

  • You need a right-hand navigation rail with grouped, nested documentation links.
  • Your app already uses shadcn sidebar and breadcrumb primitives with the standard utility helper and path alias.
  • You want a responsive sidebar shell that can collapse into the primitive's mobile interaction.

Skip it if

  • You need a standalone component with no shadcn scaffold or shared utility module.
  • You need production navigation data and router-aware links without replacing hardcoded sample content and placeholder anchors.
  • You require a clean landmark audit out of the box and cannot reconcile the nested and duplicate main landmarks in your page shell.

Bare installfails once the shadcn-style helpers are removed, so it needs that setup
Providerno provider required in the harness

For a non-shadcn project, add the sidebar and breadcrumb primitives, the shared cn utility, the @ path alias, Tailwind styles and theme variables, plus Radix UI, class-variance-authority, and Lucide React. Retain the included sidebar provider around the layout.
