Fixed 2 issues:
1. Top Padding Gap (pt-16 → removed)
Problem: Mobile fullscreen had pt-16 padding creating gap at top
Cause: Redundant padding when header is hidden in fullscreen
Solution: Removed pt-16 from mobile fullscreen layout
Before:
<div className="flex flex-1 flex-col min-h-0 pt-16">
After:
<div className="flex flex-1 flex-col min-h-0">
Result: No gap, submenu starts at top-0 ✓
2. Exit/Logout Buttons in More Page
Problem: No way to exit fullscreen or logout from mobile
Solution: Added context-aware button to More page
WP-Admin Mode:
- Shows "Exit Fullscreen" button
- Exits fullscreen mode (back to normal WP-admin)
Standalone Mode (PWA):
- Shows "Logout" button
- Redirects to WP-admin login
Implementation:
- Created AppContext to provide isStandalone and exitFullscreen
- Wrapped Shell with AppProvider
- More page uses useApp() to get context
- Conditional rendering based on mode
Files Modified:
- App.tsx: Removed pt-16, added AppProvider
- AppContext.tsx: New context for app-level state
- More/index.tsx: Added Exit/Logout button
Result:
✅ No top gap in mobile fullscreen
✅ Exit fullscreen available in WP-admin mode
✅ Logout available in standalone mode
✅ Clean, functional mobile UX! 🎯
THE BIGGER PICTURE - Root Cause Analysis:
Problem Chain:
1. FABContext value recreated every render
2. All FAB consumers re-render
3. Dashboard re-renders
4. useFABConfig runs
5. Creates new icon/callbacks
6. Triggers FABContext update
7. INFINITE LOOP!
The Bug (in BOTH contexts):
<Context.Provider value={{ config, setFAB, clearFAB }}>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
NEW object every render!
Every time Provider re-renders:
- Creates NEW value object
- All consumers see "new" value
- All consumers re-render
- Causes more Provider re-renders
- INFINITE LOOP!
The Fix:
const setFAB = useCallback(..., []); // Stable function
const clearFAB = useCallback(..., []); // Stable function
const value = useMemo(() => ({ config, setFAB, clearFAB }), [config, setFAB, clearFAB]);
^^^^^^^
Only creates new object when dependencies actually change!
<Context.Provider value={value}>
^^^^^^^
Stable reference!
Why This is Critical:
Context is at the TOP of the component tree:
App
└─ FABProvider ← Bug here affects EVERYTHING below
└─ PageHeaderProvider ← Bug here too
└─ DashboardProvider
└─ Shell
└─ Dashboard ← Infinite re-renders
└─ Charts ← Break from constant re-renders
React Context Performance Rules:
1. ALWAYS memoize context value object
2. ALWAYS use useCallback for context functions
3. NEVER create inline objects in Provider value
4. Context updates trigger ALL consumers
Fixed Contexts:
1. FABContext - Memoized value, callbacks
2. PageHeaderContext - Memoized value, callbacks
Before:
Every render → new value object → all consumers re-render → LOOP
After:
Only config changes → new value object → consumers re-render once → done
Result:
✅ No infinite loops
✅ No unnecessary re-renders
✅ Clean console
✅ Smooth performance
✅ All features working
Files Modified:
- FABContext.tsx: Added useMemo and useCallback
- PageHeaderContext.tsx: Added useMemo and useCallback
- useFABConfig.tsx: Memoized icon and callbacks (previous fix)
- App.tsx: Fixed scroll detection with useRef (previous fix)
All infinite loop sources now eliminated!
Implemented mobile-optimized navigation structure:
1. Bottom Navigation (Mobile Only)
- 5 items: Dashboard, Orders, Products, Customers, More
- Fixed at bottom, always visible
- Thumb-friendly positioning
- Active state indication
- Hidden on desktop (md:hidden)
2. More Menu Page
- Overflow menu for Coupons and Settings
- Clean list layout with icons
- Descriptions for each item
- Chevron indicators
3. FAB (Floating Action Button)
- Context-aware system via FABContext
- Fixed bottom-right (72px from bottom)
- Hidden on desktop (md:hidden)
- Ready for contextual actions per page
4. FAB Context System
- Global state for FAB configuration
- setFAB() / clearFAB() methods
- Supports icon, label, onClick, visibility
- Allows pages to control FAB behavior
5. Layout Updates
- Added pb-14 to main for bottom nav spacing
- BottomNav and FAB in mobile fullscreen layout
- Wrapped app with FABProvider
Structure (Mobile):
┌─────────────────────────────────┐
│ App Bar (will hide on scroll) │
├─────────────────────────────────┤
│ Page Header (sticky, contextual)│
├─────────────────────────────────┤
│ Submenu (sticky) │
├─────────────────────────────────┤
│ Content (scrollable) │
│ [+] FAB │
├─────────────────────────────────┤
│ Bottom Nav (fixed) │
└─────────────────────────────────┘
Next Steps:
- Implement scroll-hide for app bar
- Add contextual FAB per page
- Test on real devices
Files Created:
- BottomNav.tsx: Bottom navigation component
- More/index.tsx: More menu page
- FABContext.tsx: FAB state management
- FAB.tsx: Floating action button component
- useScrollDirection.ts: Scroll detection hook
Files Modified:
- App.tsx: Added bottom nav, FAB, More route, providers
