[Docs] Missing left sidebar navigation on all documentation pages on Mobile and smaller devices

🐛 Mobile Docs Missing Navigation Sidebar

Problem

On mobile devices, the documentation site (https://reactnative.run/docs and all sub-pages) does not display any sidebar or navigation menu.

Currently, users can only see:

• The main content
• The top header

There is no way to:

• Browse the full list of documentation sections (~20+ pages)
• Navigate between pages (Quick Start, Architecture, HMR, Expo Router, API Reference, etc.)
• Understand the overall structure of the documentation

Current Behavior

• Only page content is visible on mobile
• No sidebar or navigation tree
• No active link highlighting
• Poor discoverability of other docs pages

Expected Behavior

A responsive mobile navigation system that:

• Provides access to the full documentation hierarchy
• Uses a hamburger menu or drawer pattern
• Maintains active link highlighting
• Keeps the desktop sidebar experience unchanged

Proposed Solution

I would like to work on this issue and implement a mobile-friendly sidebar / floating bar.

Planned approach:

• Make the sidebar responsive in website/src/app/docs/layout.tsx
• Add a hamburger menu + drawer or floating bar (Tailwind-based)
• Ensure active link highlighting
• Keep UI consistent with the existing design system
• Focus on a minimal, clean, and performant implementation

Additional Notes

• No impact to desktop layout
• Changes will be lightweight and scoped only to docs navigation

I’m happy to start with a minimal working version and iterate based on feedback.

Hey @sanketsahu ! 🖐️

Quick questions:
Is the missing mobile sidebar intentional?
If not, would you be open to a fix?
Any preferred approach for mobile? (hamburger drawer, slide-in menu, floating bar menu etc.)
Anything specific I should keep in mind before starting?

If it's okay, I'd like to work on this and open a PR .
Let me know your thoughts! Happy to adjust the approach based on your feedback.
Thanks!
