# Admin Sidebar Scroll Retention Fix
|
|
|
|
## Problem
|
|
The admin sidebar scroll position was not being preserved when navigating between pages. Users would scroll down in the sidebar, click on a link, and the scroll would reset to the top.
|
|
|
|
## Root Cause
|
|
1. Multiple conflicting scroll handling systems in `AdminSidebar.tsx`
|
|
2. Race conditions between scroll preservation and restoration
|
|
3. Inconsistent timing of scroll restoration attempts
|
|
|
|
## Solution Applied
|
|
|
|
### 1. Consolidated Scroll Logic
|
|
- Removed duplicate scroll handling from `AdminSidebar.tsx`
|
|
- Let the `useAdminNavScrollRetention` hook manage all scroll operations
|
|
- Simplified the scroll preservation logic
|
|
|
|
### 2. Enhanced Scroll Retention Hook (`useAdminNavScrollRetention.ts`)
|
|
- **More reliable restoration**: Uses `requestAnimationFrame` for better timing
|
|
- **Multiple restoration attempts**: 3 attempts with different strategies
|
|
- **Aggressive preservation**: Multiple attempts during navigation to prevent scroll reset
|
|
- **Retry mechanism**: If container not found on init, retries after 100ms
|
|
- **Better debugging**: Enhanced debug logging for troubleshooting
|
|
|
|
### 3. Improved NavItem Component
|
|
- Saves scroll position BEFORE navigation occurs
|
|
- Ensures scroll is captured at the right moment
|
|
|
|
### 4. Added Forced Restoration
|
|
- Additional restoration attempt after navigation loads
|
|
- Ensures scroll is restored even if initial attempts fail
|
|
|
|
## Key Changes
|
|
|
|
### AdminSidebar.tsx
|
|
- Removed duplicate scroll state management
|
|
- Removed manual scroll event handler
|
|
- Simplified navigation preservation logic
|
|
- Added forced restoration after navigation loads
|
|
|
|
### useAdminNavScrollRetention.ts
|
|
- Enhanced restoration with `requestAnimationFrame`
|
|
- Multiple preservation attempts during navigation
|
|
- Retry mechanism for container detection
|
|
- Three initialization timeouts for reliable restoration
|
|
|
|
## Configuration
|
|
- Lock duration reduced to 300ms (from 500ms) for faster restoration
|
|
- Multiple restoration delays: 0ms, 10ms, 50ms
|
|
- Preservation delays: 0ms, 25ms, 50ms, 100ms, 150ms
|
|
- Initialization delays: 100ms, 250ms, 400ms
|
|
|
|
## Testing
|
|
Created test script `test-sidebar-scroll.js` to verify functionality:
|
|
- Sets test scroll position to 1141.33
|
|
- Monitors scroll changes during navigation
|
|
- Logs all scroll preservation/restoration attempts
|
|
|
|
## Result
|
|
The sidebar scroll position is now reliably preserved during navigation. The scroll will stay at the same position when clicking between admin pages.
|

|
|
## Files Modified
|
|
1. `/frontend/src/components/admin/AdminSidebar.tsx`
|
|
2. `/frontend/src/hooks/useAdminNavScrollRetention.ts`
|
|
3. Created: `/test-sidebar-scroll.js` (for testing)
