Slide-in Drawer - Multi-Position

Advanced slide-in drawer with three positions (left, right, bottom). Smooth cubic-bezier spring animations, glassmorphism backdrop blur, and configurable drawer width. Touch-optimized for mobile with responsive breakpoints.

Multi-position drawer: Left, right, and bottom drawer positions with smooth slide-in animations. CSS cubic-bezier spring physics for native-feeling transitions.
Glassmorphism backdrop: Beautiful blur effects using backdrop-filter CSS. Semi-transparent overlay with adjustable opacity for depth perception.
Responsive design: Drawer width adjusts for different screen sizes. Mobile-first approach with touch-optimized interactions.
Accessibility: ARIA attributes, keyboard navigation, focus trapping, and screen reader support. Semantic HTML structure.
Customizable: CSS variables for colors, transitions, and dimensions. Easy theming and branding integration.

Swipe Gestures - Touch Interactions

Native mobile swipe-to-close functionality with touch event handling. Direction-aware swipe detection, configurable threshold, and haptic feedback integration. Works for all drawer positions.

Touch event handling: Native touchstart and touchend events for swipe detection. Passive event listeners for optimal performance.
Direction-aware: Different swipe directions for each drawer position. Swipe left for right drawer, right for left drawer, down for bottom drawer.
Configurable threshold: Adjustable swipe distance threshold for activation. Prevents accidental closures.
Haptic feedback: Vibration API integration for tactile feedback. Light vibration on swipe completion.
Cross-platform: Works on iOS, Android, and touch-enabled desktop browsers. Fallback to mouse events for testing.

Dark/Light Theme - Persistent Switching

Seamless theme switching between dark and light modes. CSS custom properties for dynamic theming, localStorage persistence, system preference detection, and smooth transitions.

CSS custom properties: Dynamic color switching using CSS variables. Smooth transitions between theme changes.
localStorage persistence: Theme preference saved and restored across sessions. Automatic theme detection on page load.
System preference: Respects prefers-color-scheme media query. Falls back to user preference if set.
Icon switching: Dynamic icon updates (moon/sun) to reflect current theme. Visual feedback for theme state.
Complete theming: All UI elements themed including drawer, overlay, buttons, and text. Consistent visual experience.

Nested Drawers - Multi-Level Navigation

Multi-level navigation with nested drawers. Slide-in sub-menus within active drawer, back navigation, smooth transitions, and state management. Perfect for complex app navigation.

Multi-level navigation: Nested drawers slide in from right within main drawer. Supports unlimited nesting levels.
Smooth transitions: CSS transforms for nested drawer animations. Maintains context with parent drawer visible.
Back navigation: Dedicated back button for returning to parent level. Keyboard support for navigation.
State management: Proper state handling for nested drawer visibility. Prevents multiple drawers being open.
Mobile-optimized: Touch-friendly navigation with large tap targets. Gesture support for nested navigation.

Custom Context Menu - Right-Click Actions

Custom context menu system with glassmorphism design. Right-click and long-press support, dynamic positioning, menu actions, and haptic feedback. Replaces default browser menu.

Custom context menu: Beautiful glassmorphism design with blur effects. Replaces default browser context menu.
Touch support: Long-press support for mobile devices. Right-click support for desktop browsers.
Dynamic positioning: Intelligent positioning to stay within viewport. Automatic adjustment for screen edges.
Menu actions: Configurable menu items with icons. Support for dangerous actions with visual warnings.
Haptic feedback: Vibration on menu open and action selection. Enhanced user experience on mobile devices.

Drag & Drop - Menu Reordering

Drag-and-drop functionality for reordering menu items. Visual feedback during drag, localStorage persistence, hover states, and smooth animations. Full touch support.

Drag and drop: HTML5 Drag and Drop API implementation. Visual feedback with opacity changes and border indicators.
Touch support: Full touch support for mobile devices. Long-press to initiate drag on touch screens.
Visual feedback: Drag-over states with border indicators. Smooth animations for drop operations.
Persistence: Menu order saved to localStorage. Automatic restoration on page load.
Accessibility: Keyboard alternatives for drag operations. Screen reader announcements for reordering.

Haptic Feedback - Vibration API

Haptic feedback integration using Vibration API. Light and heavy vibration patterns, touch interaction feedback, error and success states, and device compatibility checking.

Vibration API: Native haptic feedback using navigator.vibrate. Device compatibility checking.
Feedback patterns: Light vibration for button clicks, heavy for important actions, custom patterns for errors.
Touch interactions: Haptic feedback for all touch interactions. Enhanced user experience on mobile devices.
State feedback: Different vibration patterns for success, error, and warning states. Non-visual feedback.
Performance: Optimized vibration timing. Battery-conscious implementation with minimal usage.

Skeleton Loaders - Content Loading

Beautiful skeleton loading states with shimmer animations. Simulated API calls with 2-second delay, fade-in animations for content, and responsive card layouts.

Skeleton loaders: Shimmer animation effects for loading states. CSS keyframe animations for smooth transitions.
API simulation: Mock API calls with realistic loading delays. Promise-based implementation with error handling.
Fade-in content: Smooth fade-in animations when content loads. Staggered animations for multiple cards.
Responsive layout: Card-based layout that adapts to screen size. Mobile-first design approach.
Error handling: Graceful error states with retry functionality. User-friendly error messages.
