A ready-made Vertical Nav Sections UI you can fork, run, and customize with the prompt pack below.
What's actually inside
The honest engineer's breakdown — what the Vertical Nav Sectionstemplate does, how it's wired, and where it's opinionated.
The Vertical Nav Sections template is a full sidebar component for SaaS dashboards — not a stub or a single list, but a complete sidebar system with collapsible sections, animated chevrons, active route detection, and a pinned UserFooter. The SidebarNav outer container is sticky-positioned with overflow-y-auto so it scrolls independently from the main content area. Each NavSection has its own open/closed state managed by useState, toggled by a CollapseToggle chevron button animated by Framer Motion. The SectionContent container uses a height-from-zero Framer Motion animation to expand and collapse NavItems smoothly.
NavItem components highlight the active route by comparing their href to the current pathname via usePathname() from next/navigation — giving you client-side active state that updates on every Next.js soft navigation without a page reload. Each NavItem supports a badge count prop (shadcn/ui Badge) for notification indicators. The UserFooter at the bottom is pinned using flex layout and shows a placeholder avatar, user name, and logout button.
The honest caveats: the sidebar has no mobile behavior — it uses a fixed pixel width (e.g., w-64) and will overflow small viewports without a responsive hidden class or mobile overlay pattern. The UserFooter is a static placeholder; it requires a prompt to wire it to Clerk or any real auth provider. The Framer Motion height animation from 0 to auto can jump instead of sliding if the layout prop is not correctly applied — a known gotcha documented below with a fix prompt.

Fork it and get it running
Forking the Vertical Nav Sections template and customizing it to your app's routes takes about five minutes. The main task after forking is swapping the placeholder nav data array for your own sections and routes — a free code edit that costs no V0 credits.
Fork the template from V0 community
Open https://v0.dev/chat/community/s6KKjnsSFAw in your browser. The community page shows a live Vercel Sandbox preview of the sidebar on the right side. Click the Fork button in the top-right corner — V0 copies the project into your account and opens the full editor with the chat panel, code editor, and preview pane.
Tip: A free V0 account is sufficient to fork and preview. Forking costs one credit.
You should see: The project opens in your V0 editor with the SidebarNav visible in the Vercel Sandbox preview.
Test the expand/collapse animations and active state
In the Vercel Sandbox preview, click each NavSection heading to expand and collapse sections — watch the CollapseToggle chevron rotate and SectionContent slide open. Then click individual NavItems and verify the active route highlight updates correctly. If the active highlight does not change in the preview sandbox, that is expected — the preview URL does not change on NavItem click, so the usePathname() comparison will only show the active state correctly in a real deployed app.
Tip: Active state will work correctly once the component is embedded in a real Next.js app where the route actually changes on navigation.
You should see: NavSections expand and collapse with smooth Framer Motion animation; CollapseToggle chevron rotates on toggle.
Replace placeholder nav data with your app's routes
Open the Code tab in the V0 editor and look for the nav data array — typically an array of objects with a section name and items array containing { label, href, icon } objects. Replace all placeholder sections and items with your actual app routes, section names, and Lucide icon names. For example: { section: 'Main', items: [{ label: 'Dashboard', href: '/dashboard', icon: 'LayoutDashboard' }] }. This is a free direct code edit — no credits consumed.
Tip: All icon names must match Lucide React's export names exactly (PascalCase, e.g., 'BarChart2', 'Settings', 'HelpCircle'). Check lucide.dev for the full list.
You should see: SidebarNav displays your custom sections, labels, and icons in the preview after the hot reload.
Set the sidebar color in Design Mode
Press Option+D (Mac) to enter V0's Design Mode. Click the SidebarNav background to see its current Tailwind class (often bg-zinc-950 for dark or bg-white for light). Click the class badge and type your preferred background — for example bg-slate-900 or bg-white. Do the same for NavItem hover states and the UserFooter area. Exit Design Mode with Escape. No credits are consumed for Design Mode edits.
Tip: For a SaaS dashboard, bg-zinc-900 (dark sidebar) with main content in bg-zinc-950 gives a Vercel-like depth contrast.
You should see: SidebarNav renders with your chosen background color without spending any prompt credits.
Publish to Vercel and export to GitHub
Click Share in the V0 top navigation, then the Publish tab, then 'Publish to Production'. V0 deploys the project to Vercel in 30–60 seconds and provides a live URL. To bring the sidebar into your existing codebase, open the Git panel in V0, click 'Connect GitHub', authorize V0, and choose or create a repository. V0 auto-creates a branch named v0/main-{hash} with the full project committed. Merge the pull request on GitHub to sync the SidebarNav component into your project.
Tip: To add a custom domain, open vercel.com/dashboard → select the project → Settings → Domains → Add Domain.
You should see: A live Vercel URL is generated; a GitHub branch is created and ready to merge into your codebase.
The prompt pack
Copy-paste these straight into v0's chat to customize the Vertical Nav Sectionstemplate. Each one names this template's own components — no generic filler.
Replace nav items with my app's routes
Replaces placeholder nav data with a real three-section SaaS dashboard structure, using Lucide icons and active route detection.
Update the SidebarNav data array to match my app's structure. Create three NavSections: 'Main' with items [Dashboard (/dashboard, icon: LayoutDashboard), Projects (/projects, icon: FolderKanban), Reports (/reports, icon: BarChart2)], 'Settings' with items [Profile (/settings/profile, icon: User), Security (/settings/security, icon: Shield), Billing (/settings/billing, icon: CreditCard)], and 'Support' with items [Help Center (/help, icon: HelpCircle), Contact (/contact, icon: MessageSquare)]. Use Lucide React icons that are already imported. Ensure each NavItem calls usePathname() from next/navigation to highlight the active route.
Add notification badge counts to NavItems
Adds inline notification badges to specific NavItems so users can see unread counts directly in the SidebarNav without opening each section.
Add a badgeCount prop to the NavItem component. When badgeCount is greater than 0, render a shadcn/ui Badge with variant='secondary' positioned inline-right of the item label text, showing the numeric count in a small rounded pill style. Hardcode badgeCount={5} on the Projects NavItem and badgeCount={2} on the Reports NavItem to demonstrate the pattern. The badge should not render at all when badgeCount is 0 or undefined — use a conditional render rather than opacity-0.Sync expanded sections to URL searchParams
Makes the SidebarNav section expand/collapse state shareable and refresh-safe via URL query parameters without any localStorage or server state.
Persist which NavSections are currently expanded in the URL as a comma-separated query parameter: ?sections=main,settings. On mount, read this parameter with useSearchParams() from next/navigation and expand the matching sections by initializing their open state to true. When any NavSection toggles, call router.replace() with the updated sections list included in the searchParams — preserve any other existing query parameters. This way, sharing or refreshing the URL preserves the exact sidebar state.
Show nav items based on Clerk user role
Adds role-based visibility to the SidebarNav so admins see extra sections and viewers see restricted items — all using Clerk's existing user metadata.
Use Clerk's useUser() hook to get the current user's publicMetadata.role from the Clerk user object. If the role is 'admin', add an additional NavSection called 'Admin' with items [User Management (/admin/users, icon: Users), Audit Log (/admin/audit, icon: ClipboardList)] after the existing sections in SidebarNav. If the role is 'viewer', render the Projects NavItem with opacity-40 and pointer-events-none Tailwind classes, and add a shadcn/ui Tooltip with the message 'Upgrade your plan to access Projects' that appears on hover over the disabled NavItem.
Wire UserFooter to Clerk auth with real user data
Replaces the static UserFooter placeholder with a fully functional Clerk-powered user identity block, including profile management and sign-out.
Replace the UserFooter placeholder content with live Clerk user data. Use Clerk's useUser() hook to access user.imageUrl, user.fullName, and user.primaryEmailAddress.emailAddress. Replace the placeholder avatar with Clerk's <UserButton /> component — this gives you a built-in profile popup with account management. Add a separate Sign Out button below UserButton that calls signOut() from Clerk's useAuth() hook. While user data is loading (isLoaded === false), show shadcn/ui Skeleton loaders for the avatar circle, name line, and email line to prevent layout shift.
Gotchas when you extend it
The failures people actually hit when they push this template past its defaults — and the exact fix for each.
Framer Motion height animation from 0 to 'auto' causes NavSection content to jump instead of slideWhy: Animating height from 0 to 'auto' in Framer Motion requires the layout prop or an explicit measured pixel height — animate={{ height: 'auto' }} alone does not work reliably and causes SectionContent to snap open instead of sliding, especially when the content height is dynamic.
Fix: Add the layout prop to the SectionContent motion.div parent, set initial={{ height: 0, overflow: 'hidden' }}, and animate to height: isOpen ? 'auto' : 0. Alternatively, measure the content height with a ref and animate to the exact pixel value. Ensure overflow: 'hidden' is applied during animation so child content doesn't bleed outside.
Fix the NavSection collapse animation so it smoothly slides rather than jumping — add the Framer Motion layout prop to the SectionContent motion.div and ensure overflow: hidden is applied during the animation. If height: 'auto' does not animate, measure the child content height with a useRef and animate to the explicit pixel value instead.
Active NavItem highlight not updating on Next.js client-side navigationWhy: If NavItem compares its href to a pathname value passed down as a prop from a parent Server Component, the comparison is static and won't re-evaluate when Next.js navigates client-side. The 'use client' directive must be on the NavItem file, and usePathname() must be called directly inside NavItem.
Fix: Add 'use client' at the top of the NavItem component file. Call usePathname() from next/navigation directly inside NavItem — do not pass pathname as a prop. This ensures the hook re-evaluates on every client-side route change.
Fix the active NavItem highlight not updating on navigation — add 'use client' at the top of the NavItem file and call usePathname() from next/navigation directly inside the NavItem component instead of receiving pathname as a prop from a parent.
SidebarNav overflows the viewport on mobile and pushes main content off-screenWhy: The SidebarNav uses a fixed pixel width (e.g., w-64) without responsive hidden classes. On screens below 768px, the sidebar does not collapse and the CSS layout pushes the main content column partially or fully off-screen, making the page unusable on mobile.
Fix: Add hidden md:block to SidebarNav so it is hidden on small viewports. Add a hamburger menu button in the top bar that toggles a mobile overlay sidebar — an absolutely positioned panel that slides in from the left over the content, with a backdrop click to close.
Make the SidebarNav responsive — add hidden md:block so it is hidden on mobile, and add a hamburger button in the top navigation bar that opens a mobile overlay sidebar using absolute positioning with a semi-transparent backdrop. Clicking outside the overlay should close the sidebar.
UserFooter Clerk avatar image returns CORS error in V0 preview sandboxWhy: Clerk's CDN for user avatar images may block requests originating from the V0 Vercel Sandbox preview domain since that domain is not in Clerk's authorized referrers list. The image renders correctly in the deployed production environment but shows a broken image in V0 preview.
Fix: This is a preview-only limitation. Add an onError handler to the avatar img element that swaps the src to a generated placeholder (e.g., from ui-avatars.com using the user's initials) when the Clerk avatar fails to load. The real Clerk imageUrl will work correctly in your deployed app.
Add a fallback avatar in the UserFooter for when the Clerk user imageUrl fails to load in preview — add an onError handler on the img element that replaces the src with a ui-avatars.com URL constructed from the user's initials.
Template vs. custom — the honest call
A forked template gets you far, fast. Here's where it holds up, and where you'll outgrow it.
The template is enough when
- You need a standard SaaS left sidebar with 2–4 collapsible sections and 5–15 total nav items
- Your navigation structure is fixed and defined in code — not pulled from a CMS or database at runtime
- You want Framer Motion collapse animation without building height animations from scratch
- You are shipping a dashboard MVP within the next week and can refine the sidebar in a later iteration
Go custom when
- You need infinite nesting beyond two levels — this template is one section level deep, and three or more levels require custom recursive components
- You need server-side access control rendering different nav trees per role at the database query level, not just client-side conditional rendering
- You need users to reorder or customize their own sidebar navigation with drag-and-drop — that requires a separate persistence layer and drag library
If you need the vertical nav wired to Clerk roles, Supabase permissions, and dynamic section items from a CMS, RapidDev can deliver that as a production integration.
Frequently asked questions
Is the Vertical Nav Sections v0 template free to use?
Yes. The template is published in the V0 community and free to fork. Forking uses one of your monthly V0 credits (the free plan includes credits each month). All underlying libraries — Next.js, Tailwind CSS, Framer Motion, Lucide React, shadcn/ui — are MIT-licensed and free for any use.
Can I use this template commercially?
Yes. Once you fork the template, the code is yours with no V0 licensing restriction on commercial use. The component libraries (shadcn/ui, Framer Motion, Lucide React) are all MIT-licensed, which permits commercial use without royalties or attribution requirements.
Why does my fork show the wrong active NavItem highlight (or no highlight at all)?
This usually means the NavItem is reading pathname from a prop instead of calling usePathname() directly, or the NavItem file is missing 'use client'. In Next.js App Router, usePathname() is a client-side hook — the file that calls it must have 'use client' at the top, and the hook must be called directly in the NavItem (not passed down from a parent). See the second gotcha above for the exact fix prompt.
Why does the NavSection expansion jump instead of sliding in my fork?
Animating from height 0 to 'auto' in Framer Motion requires either the layout prop on the parent or an explicitly measured pixel height. Without it, the SectionContent snaps open instead of sliding. Use the fix prompt in the gotchas section above — it adds the layout prop and ensures overflow: hidden is applied during the animation to prevent content bleeding.
Why does my fork break in V0 preview after I add Clerk authentication?
The most common issue is the Clerk avatar CDN blocking the V0 Vercel Sandbox preview domain, causing broken images in preview (but not in production). A secondary issue is calling Clerk hooks in files that are Server Components — add 'use client' to any file that uses useUser(), useAuth(), or UserButton. See the UserFooter CORS gotcha above for the avatar fallback fix.
How do I make the sidebar show on mobile?
By default, the SidebarNav uses a fixed pixel width that overflows small screens. Add 'hidden md:block' to the SidebarNav to hide it on mobile, then add a hamburger button in your top navigation bar that toggles a mobile overlay sidebar. Use the gotcha fix prompt above to generate this pattern automatically in V0.
Can I connect the UserFooter to my actual user account?
Yes — the UserFooter is a placeholder by design. Use the advanced prompt in the pack above to wire it to Clerk's useUser() hook, which pulls the user's real name, email, and avatar. The prompt also adds Clerk's UserButton component for a built-in profile popup and a sign-out button.
Can RapidDev customize this sidebar for my SaaS app?
Yes. RapidDev can extend this V0 prototype with Clerk role-based nav visibility, dynamic section items from a Supabase CMS, and a mobile-responsive overlay sidebar — delivered as a production-ready integration. Learn more at rapidevelopers.com.
