+
+## Positioning System
+
+### Box UI Elements (TetherComponent)
+
+- Positioning Props:
+  - attachment: 'top left' | 'top right' | etc.
+  - targetAttachment: 'bottom left' | 'bottom right' | etc.
+  - constraints: Array of positioning rules
+    ```javascript
+    constraints: [
+      {
+        to: 'scrollParent' | 'window',
+        attachment: 'together',
+        pin: boolean,
+      },
+    ];
+    ```
+  - Manual positioning calculation
+  - Complex constraint system
+  - Less intuitive positioning configuration
+
+### Blueprint (Radix UI Positioning)
+
+- Positioning Props:
+
+  - side: 'top' | 'right' | 'bottom' | 'left'
+  - align: 'start' | 'center' | 'end'
+  - avoidCollisions: boolean
+  - collisionPadding: number | Padding
+  - sticky: 'partial' | 'always'
+  - sideOffset: number
+  - alignOffset: number
+
+- Benefits:
+  - More semantic positioning system
+  - Automatic collision detection
+  - Better viewport containment
+  - Simpler configuration
+  - Built-in animations
+  - Improved performance
+  - Better handling of dynamic content
+
+### Migration Considerations
+
+- TetherComponent to Radix UI transition:
+  - Different positioning terminology
+  - Simpler constraint system
+  - More predictable behavior
+  - Better performance characteristics
+  - Improved accessibility integration

+## Accessibility and Keyboard Navigation
+
+### WAI-ARIA Menu Button Pattern Implementation
+
+- Box UI Elements:
+
+  - Manual ARIA attribute management
+  - Basic WAI-ARIA menu button compliance
+  - Custom keyboard navigation implementation
+  - Manual focus management
+
+- Blueprint/Radix UI:
+  - Built-in WAI-ARIA menu button compliance
+  - Comprehensive ARIA attribute handling
+  - Enhanced keyboard navigation
+  - Automatic focus management
+  - Better screen reader support
+
+### Keyboard Navigation
+
+- Box UI Elements:
+
+  - Space/Enter: Toggle menu
+  - Arrow Right: Open menu
+  - Arrow Down: Open menu and focus first item
+  - Arrow Up: Open menu and focus last item
+  - Escape: Close menu
+  - Manual focus trap implementation
+
+- Blueprint:
+  - Space/Enter: Open menu and focus first item
+  - Arrow Down: Open menu and focus first item
+  - Arrow Up: Open menu and focus last item
+  - Arrow Right: Open submenu
+  - Arrow Left: Close submenu
+  - Escape: Close menu
+  - Home: Focus first item
+  - End: Focus last item
+  - Type character: Move to matching item
+  - Automatic focus trap management
+
+### Focus Management
+
+- Box UI Elements:
+
+  - Manual focus management through refs
+  - Custom focus trap implementation
+  - Manual focus restoration
+  - Document click handlers for blur
+
+- Blueprint:
+  - Automatic focus management through Radix UI
+  - Built-in focus trap
+  - Automatic focus restoration
+  - Better handling of nested focus contexts
+  - Improved focus restoration on menu close

+
+## Core Props Mapping
+
+### Box UI Elements Props -> Blueprint Equivalent
+
+1. bodyElement (HTMLElement) -> container (HTMLElement)
+
+   - Maps to DropdownMenuPortal's container prop
+   - Both control where menu content is rendered
+   - Blueprint provides more flexible portal handling
+
+2. children (React.Node) -> Split across components
+
+   - First child -> DropdownMenuTrigger children
+   - Second child -> DropdownMenuContent children
+   - Blueprint requires explicit component structure
+   - Improves component composition and reusability
+
+3. constrainToScrollParent (boolean) -> collisionBoundary (Boundary)
+
+   - Maps to DropdownMenuContent's collisionBoundary
+   - Different approach to scroll parent containment
+   - Blueprint offers more granular collision control
+
+4. constrainToWindow (boolean) -> avoidCollisions (boolean)
+
+   - Maps to DropdownMenuContent's avoidCollisions
+   - Blueprint handles collision avoidance automatically
+   - More robust positioning system through Radix UI
+
+5. constrainToWindowWithPin (boolean) -> sticky (boolean)
+
+   - Maps to DropdownMenuContent's sticky prop
+   - Controls whether menu stays within viewport
+   - Blueprint provides better viewport containment
+
+6. isResponsive (boolean) -> No direct equivalent
+
+   - Blueprint handles responsive behavior automatically
+   - Uses modern CSS features for responsiveness
+   - Consider using CSS media queries instead
+
+7. isRightAligned (boolean) -> align="end" (string)
+
+   - Maps to DropdownMenuContent's align prop
+   - Blueprint offers more alignment options
+   - More semantic alignment system
+
+8. onMenuClose (function) -> onOpenChange (function)
+
+   - Maps to DropdownMenuRoot's onOpenChange

+   - Blueprint consolidates state management
+   - More consistent event handling
+
+10. tetherAttachment (string) -> side, align (string)
