# Cut Public View Implementation
|
||
|
||
## Summary
|
||
|
||
Successfully implemented multi-cut functionality for the public map view with auto-display of public cuts and multi-select dropdown controls.
|
||
|
||
## Features Implemented
|
||
|
||
### 1. Auto-Display Public Cuts
|
||
- All cuts marked as public (`is_public = true` or `Public Visibility = true`) are automatically displayed when the map loads
|
||
- Uses the existing backend API endpoint `/api/cuts/public`
|
||
- Handles different field name variations (normalized data access)
|
||
|
||
### 2. Multi-Select Dropdown (Desktop)
|
||
- Replaces single-cut selector with multi-select checkbox interface
|
||
- Shows "Manage map overlays..." with count when cuts are active
|
||
- Dropdown shows on focus with:
|
||
- Quick action buttons (Show All / Hide All)
|
||
- Individual checkboxes for each cut with color indicators
|
||
- Official cut badges
|
||
- Real-time updates of checkbox states
|
||
|
||
### 3. Mobile Overlay Modal
|
||
- Dedicated mobile interface for cut management
|
||
- Accessible via 🗺️ button in mobile sidebar
|
||
- Full-screen modal with:
|
||
- Show All / Hide All action buttons
|
||
- Large touch-friendly checkboxes
|
||
- Color indicators and cut names
|
||
- Official cut badges
|
||
|
||
### 4. Legend System
|
||
- Dynamic legend showing all active cuts
|
||
- Color-coded entries with cut names
|
||
- Individual remove buttons (×) for each cut
|
||
- Auto-hides when no cuts are displayed
|
||
|
||
### 5. Multi-Cut Management
|
||
- Support for displaying multiple cuts simultaneously
|
||
- Individual toggle functionality
|
||
- Proper layer management and cleanup
|
||
- State persistence across UI interactions
|
||
|
||
## Files Modified

```
|
||
|
||
### CSS (`map-controls.css`)
|
||
- Multi-select dropdown styles (`.cut-checkbox-container`, `.cut-checkbox-item`)
|
||
- Legend styles (`.cut-legend`, `.legend-cut-item`)
|
||
- Mobile overlay styles (`.mobile-overlay-list`, `.overlay-actions`)
|
||
- Color box indicators (`.cut-color-box`)
|
||
- Responsive mobile adjustments
|
||
|
||
### JavaScript
|
||
|
||
#### `cut-controls.js` - Enhanced with:
|
||
- `autoDisplayAllPublicCuts()` - Auto-display public cuts on load
|
||
- `populateCutSelector()` - Multi-select checkbox dropdown
|
||
- `updateMultipleCutsUI()` - Update UI for multiple active cuts
|
||
- `showMultipleCutsLegend()` - Dynamic legend display
|
||
- Global functions: `toggleCutDisplay()`, `showAllCuts()`, `hideAllCuts()`
|
||
- Mobile overlay functions: `openMobileOverlayModal()`, `populateMobileOverlayOptions()`
|
||
|
||
#### `cut-manager.js` - Enhanced with:
|
||
- Enhanced `displayCut()` method with multi-cut support
|
||
- `isCutDisplayed()` - Check if cut is displayed
|
||
- `hideCutById()` - Hide individual cuts by ID
|
||
- `hideAllCuts()` - Hide all displayed cuts
|
||
- `getDisplayedCuts()` - Get array of currently displayed cuts
|
||
- Proper normalization of cut data fields
|
||

|
||
|
||
## API Integration
|
||
|
||
Uses existing backend endpoints:
|
||
- `GET /api/cuts/public` - Fetch all public cuts
|
||
- Cut data normalization handles various field name formats:
|
||
- `id` / `Id` / `ID`
|
||
- `name` / `Name`
|
||
- `is_public` / `Public Visibility`
|
||
- `is_official` / `Official Cut`
|
||
- `geojson` / `GeoJSON` / `GeoJSON Data`
|
||
|
||
## User Experience
|
||
|
||
### Desktop Workflow:
|
||
1. Public cuts auto-display on map load
|
||
2. Selector shows "X overlays active" when cuts are displayed
|
||
3. Click selector to open checkbox dropdown
|
||
4. Use checkboxes to toggle individual cuts on/off
|
||
5. Use "Show All" / "Hide All" for quick actions
|
||
6. Legend shows active cuts with remove buttons
|
||
|
||
### Mobile Workflow:
|
||
1. Public cuts auto-display on map load
|
||
2. Tap 🗺️ button to open overlay modal
|
||
3. Use large checkboxes to toggle cuts
|
||
4. Use "Show All" / "Hide All" action buttons
|
||
5. Close modal to return to map
|
||
|
||
## Error Handling
|
||
|
||
- Graceful fallback when API fails (uses mock data for testing)
|
||
- Proper error logging for failed cut displays
|
||
- Safe handling of missing DOM elements
|
||
- Validation of GeoJSON data before display
|
||
|
||
