# File Tree Sidebar V0 Template: Build VS Code-Style Nav in Next.js - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The File Tree Sidebar v0 template gives you a fully interactive recursive file tree built in Next.js 14+ and TypeScript — no third-party tree library required. It ships with a FileTreeSidebar, recursive TreeNode with expand/collapse, FolderIcon/FileIcon from lucide-react, ActiveFileHighlight, shadcn/ui ScrollArea, and a right-click FileContextMenu. Fork it, replace the static tree data with your structure, and get a VS Code-style sidebar in your app today. ## Frequently asked questions ### Is this file tree template free? Yes. V0 community templates are free to fork with a free V0 account. You can use the code in personal and commercial projects without licensing fees. ### Can I use this template commercially — for example, inside a paid SaaS product? Yes. V0 community templates carry no commercial-use restrictions. You own the forked code and can ship it as part of any paid product. ### Why does my fork break in the V0 preview after adding drag-and-drop? Drag-and-drop libraries like @dnd-kit access window and document during module initialization. V0's preview sandbox runs SSR, which fails when these browser globals are missing. Wrap your draggable component in next/dynamic with ssr: false — see the gotcha above — and verify on the deployed Vercel URL instead. ### The tree crashes the browser tab when I give it real data. What is happening? The recursive TreeNode component does not have a depth cap by default. If your tree data has circular references or is very deep, it will render infinitely. Paste the infinite loop fix prompt from the Gotchas section into V0 chat to add a maxDepth guard. ### How do I connect the file tree to a real file system or cloud storage? The static constants file approach only works for small, known file structures. For real data, use the Supabase Storage prompt from the prompt pack above to fetch file paths from a bucket, or create a Next.js API route that reads from your storage provider and returns the nested tree structure. ### Can I use this for a documentation site where the sidebar IS the file tree? Yes, but the Documentation Starter template is better suited — it pairs the file tree pattern with MDX rendering, BreadcrumbNav, and PrevNextNav specifically for docs. This template is optimized for file manager and dev tool UIs. ### Folder expand state resets when I search or filter the tree. How do I fix it? Local useState in each TreeNode resets when the parent re-renders. Lift the expanded state to a Map in the parent FileTreeSidebar component — the Gotchas section above has the exact fix prompt to paste into V0 chat. ### Can RapidDev help connect this file tree to Supabase Storage or S3? Yes. RapidDev connects V0 file tree UIs to real storage backends with permission checks, upload flows, and real-time updates.
