// 2. "MORE" dropdown with all other pages
// 3. Hover over "MORE" to see all pages


// API ENDPOINT FOR CUSTOM USE
// ================================

// - action=get_all_pages          → returns all pages
// - action=toggle_featured        → toggle page featured status
//   (requires: page_id, is_featured)


// DATABASE TABLE STRUCTURE

// 
// For production, add:
// - CSRF tokens
// - Rate limiting on API
// - Audit logging


// TROUBLESHOOTING
// ================================
// Navigation not showing?
// → Run setup_pages_table.php
// → Check pages table exists
// → Verify at least 1 page has is_featured = 1
// 
// Dropdown not appearing?
// → Check css/navigation-menu.css is loading
// → Verify WEB_BASE_PATH in header.php
// → Check browser console for errors
// 
// Database error?
// → Verify db_config.php credentials
// → Check MySQL is running
// → Verify user has CREATE TABLE permission


// FEATURE SUMMARY
// ================================
// HEADER NAVIGATION:
// • Shows up to 4 featured pages
// • Featured pages appear in menu_order
// • Clean, responsive design
// 
// DROPDOWN MENU (on hover):
// • Shows ALL pages from database
// • Featured pages marked with orange badge
// • Smooth animation and styling
// 
// ADMIN INTERFACE:
// • Add new pages to system
// • Toggle featured status
// • Change menu order
// • Delete pages
// • View statistics
// 
// DATABASE:
// • MySQL-driven (flexible, scalable)
// • Prepared statements (secure)
// • Auto timestamps
// 
// API:
// • AJAX-compatible endpoint
// • JSON responses
// • Easy to integrate with frontend


// NEXT STEPS
// ================================
// 1. Run setup_pages_table.php to create table
// 2. Go to admin_manage_pages.php to manage pages
// 3. Visit your site to see navigation in action
// 4. Customize colors/styling in css/navigation-menu.css
// 5. Read full documentation in NAVIGATION_SYSTEM_DOCUMENTATION.md


// EXAMPLE: Adding to Sidebar Menu
// ================================
// if (isset($_SESSION['is_admin']) && $_SESSION['is_admin']) {
//     echo '<li><a href="admin_manage_pages.php">Manage Pages</a></li>';
// }


// EXAMPLE: Custom Navigation Render
// ================================
// $pages = NavigationHelper::getAllPages();
// echo '<nav>';
// echo '<ul>';
// foreach ($pages as $page) {
//     $featured = $page['is_featured'] ? 'class="featured"' : '';
//     echo "<li $featured><a href='" . htmlspecialchars($page['url']) . "'>";
//     echo htmlspecialchars($page['title']);
//     echo '</a></li>';
// }
// echo '</ul>';
// echo '</nav>';


// PERFORMANCE NOTES
// ================================
// • Queries are optimized with indexes
// • Limited to 4 featured pages for UI cleanliness
// • Menu_order provides flexible sorting
// • Consider caching for high-traffic sites
