Hamburger Menu Not Opening on Mobile in Bolt App
The hamburger menu icon in your Bolt.new application is visible on mobile screens but nothing happens when users tap it. Alternatively, the menu opens once but then refuses to close, or it opens behind other page content and is invisible.
Mobile navigation is critical for user experience, and a broken hamburger menu effectively makes your entire app unusable on phones and tablets. Users cannot access any page other than the one they landed on, causing immediate bounce rates and lost conversions.
This issue is extremely common in Bolt-generated apps because the AI creates the toggle logic and CSS transitions but doesn't always handle the interaction between state management, z-index stacking, and touch events correctly on real mobile devices.
Error Messages You Might See
Cannot read property 'classList' of null
Warning: Maximum update depth exceeded
TypeError: toggle is not a function
Element is not clickable at point (x, y)
Common Causes
- State toggle not updating — The isOpen state is set but the component doesn't re-render because of a stale closure or missing dependency in the toggle function
- Z-index too low — The mobile menu panel renders behind the main content or hero section because its z-index is lower
- Click event not firing on mobile — The onClick handler works with mouse clicks but doesn't respond to touch events on iOS Safari
- CSS transition broken — The menu is set to translate off-screen but the transition property is missing, so the menu moves but is never visible
- Menu overlay blocking scroll — The menu opens but a transparent overlay prevents tapping any menu items
- Conditional rendering removes menu — Using {isOpen &&
How to Fix It
- Debug the toggle state — Add a console.log inside your toggle handler: const toggleMenu = () => { console.log('toggling', !isOpen); setIsOpen(!isOpen); } and verify it fires on tap
- Fix z-index stacking — Set the mobile menu to z-50 (or z-index: 50) and ensure parent containers don't create new stacking contexts that trap it
- Use button element for toggle — Replace div or span with a proper <button> element which handles both click and touch events natively
- Keep menu in DOM always — Instead of conditional rendering, use CSS classes to show/hide: className={`fixed inset-0 z-50 transition-transform ${isOpen ? 'translate-x-0' : '-translate-x-full'}`}
- Add backdrop and close behavior — Add a semi-transparent backdrop that closes the menu when tapped: <div onClick={() => setIsOpen(false)} className="fixed inset-0 bg-black/50 z-40" />

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
Why does my menu work on desktop but not on mobile?
Desktop browsers handle click events differently than mobile browsers. Touch events on iOS Safari have a 300ms delay and may not fire on non-interactive elements like div or span. Always use button elements for interactive controls.
How do I prevent the page from scrolling when the menu is open?
Add overflow-hidden to the body when the menu opens: useEffect(() => { document.body.style.overflow = isOpen ? 'hidden' : 'auto'; return () => { document.body.style.overflow = 'auto'; }; }, [isOpen]);
