# Sidebar Layout V0 Template: Fork It & Ship Your Nav Shell - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Sidebar Layout v0 template gives you a production-ready collapsible sidebar shell built on Next.js 14+, shadcn/ui, and TypeScript — no auth, no DB, just the nav. Fork it, drop your page content into MainContent, and deploy to Vercel in under 5 minutes. The prompt pack covers dark mode, Clerk auth wiring, role-based nav, and Supabase-persisted collapse state. ## Frequently asked questions ### Is this sidebar layout template free to use? Yes. V0 community templates are free to fork and use in personal and commercial projects. You need a free V0 account to fork. ### Can I use this template for a commercial SaaS product? Yes. V0 community templates have no commercial-use restrictions. You own the forked code and can ship it as part of any product. ### Why does my fork break in the V0 preview but work after deploying? V0 runs previews in an esm.sh sandbox that has limitations with certain packages. SSR-related errors (like the localStorage issue) may also show as red banners in preview but resolve correctly after a real Vercel deploy. Always verify functionality on the deployed URL before concluding something is broken. ### Does the sidebar template include authentication? No. The template is a pure UI shell — it has a TopBar user menu area placeholder but no auth logic. You add Clerk, NextAuth, or Supabase Auth separately using the prompt pack prompts in this guide. ### How do I add my own pages behind the sidebar? Create new page files in the app/ directory using Next.js App Router conventions (e.g. app/dashboard/page.tsx). Import and render them inside the MainContent component. The sidebar NavItems are independent — update their hrefs to match your new routes. ### The sidebar collapse state resets on every page load — how do I persist it? The template stores collapse state in React useState, which resets on refresh. Paste the 'Persist sidebar collapse state to Supabase' prompt from the prompt pack above into the V0 chat to add database-backed persistence. For a localStorage-only approach, use the 'fix_prompt' from the localStorage gotcha. ### Can RapidDev help me turn this sidebar template into a full product? Yes. RapidDev builds on V0 prototypes and adds auth-gated routes, database schemas, CI/CD pipelines, and production-ready design systems. You can learn more at rapidevelopers.com. ### Does the template work on mobile? The MobileDrawer adapts the sidebar to a Sheet overlay on small screens. The implementation is solid for basic use, but you should test your specific content in the Preview tab at a narrow width and verify the drawer closes after navigation (see the gotcha above). --- Source: https://www.rapidevelopers.com/v0-template/sidebar-layout © RapidDev — https://www.rapidevelopers.com/v0-template/sidebar-layout
