  - Location (address & city)
  - Price
  - Bedrooms & Bathrooms

- Added spinner animation

## JavaScript Functions

### Real-time Functions

```javascript
// Load properties with pagination
loadProperties(page = 1)

// Render properties grid
renderProperties(properties, page, totalPages)

// Load services with pagination
loadServices(page = 1)

// Render services grid
renderServices(services, page, totalPages)

// Add new service
saveService()

// Section navigation
activateSection(section)
```

## Usage Examples

### Accessing Admin Dashboard
```
http://localhost/nexthm/dashboards/admin-dashboard.php?section=overview
```

### Available Sections
- `?section=overview` - Statistics and overview
- `?section=users` - User management
- `?section=properties` - Properties management
- `?section=services` - Services management

### Adding a Service
1. Navigate to Admin Dashboard
2. Click "Services" in sidebar
3. Click "+ Add New Service" button
4. Fill in service details:
   - Title (required)
   - Description
   - Icon (FontAwesome class, e.g., `fas fa-home`)
   - Price (optional)
5. Click "Save Service"
6. Service appears immediately in the grid (real-time update)

## Responsive Breakpoints

```css
/* Mobile */
@media (max-width: 768px) {
  - Sidebar collapses to icon-only (60px wide)
  - Main content adjusts margin
  - Grid becomes single column
  - Labels hide on sidebar items
}

/* Tablet & Desktop */
- Full sidebar (280px)
- Grid: repeat(auto-fill, minmax(300px, 1fr))
- Multi-column layout based on screen width
```

## Database Schema

### Services Table
```sql
CREATE TABLE services (
  id INT AUTO_INCREMENT PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  description TEXT,
  icon VARCHAR(100),
  price DECIMAL(10, 2),
  status VARCHAR(50) DEFAULT 'active',
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);
```

## Real-time Update Mechanism

The dashboard implements a polling system that checks for updates every 30 seconds:

```javascript
setInterval(() => {
  if (currentSection === 'properties') {
    loadProperties(currentPropertyPage);
  } else if (currentSection === 'services') {
    loadServices(currentServicePage);
  }
}, 30000); // 30 seconds
```

This ensures that:
- New properties/services added by other admin users appear automatically
- Changes are always reflected in the current view
- No manual refresh needed

## Security Features

- Admin authorization check on all API endpoints
- Session validation required
- SQL prepared statements to prevent injection
- Input validation and sanitization
- CSRF protection via session validation

## Browser Compatibility

- Chrome 90+
- Firefox 88+
- Safari 14+
- Edge 90+
- Mobile browsers (iOS Safari, Chrome Android)

## Performance Optimization

- Lazy loading via pagination
- Grid virtualization through CSS Grid
- Efficient API calls
- Debounced window resize events
- Optimized refresh intervals (30 seconds)
