Maintaining the exact same component API +2. Preserving visual appearance +3. Adding full accessibility features +4. Keeping bundle size impact minimal + +## Evidence + +### 1. Component API Preserved + +The Radix implementation maintains 100% API compatibility: + +```tsx +// Before (still works) + + + Account Name + + + + + +``` + +**Props preserved:** +- `DropdownMenu`: `children` +- `DropdownMenu.Trigger`: `children`, `triggerClassNames`, `description` +- `DropdownMenu.Content`: `children`, `anchorPosition`, `contentClassNames` +- `DropdownMenu.Link`: `url`, `title`, `subtitle`, `iconName`, `children` + +### 2. Accessibility Audit Results + +| Feature | Original | Radix | Status | +|---------|----------|-------|--------| +| Click to open/close | Yes | Yes | Pass | +| Click outside to close | Yes | Yes | Pass | +| Escape key to close | No | Yes | **NEW** | +| Arrow key navigation | No | Yes | **NEW** | +| Tab navigation | Partial | Full | **Improved** | +| ARIA roles | None | `menu`, `menuitem` | **NEW** | +| Screen reader support | None | Full | **NEW** | +| Focus management | None | Proper focus trap | **NEW** | +| `aria-expanded` state | No | Yes | **NEW** | +| Keyboard activation (Enter/Space) | No | Yes | **NEW** | + +### 3. Visual Appearance + +The visual styling is identical to the original: +- Same rounded corners (`rounded-lg`) +- Same shadow (`ui-shadow-md-soft`) +- Same border styling (`border-neutral-400`) +- Same hover states on items +- Same dark mode support + +### 4. Bundle Impact + +| Metric | Before | After | Change | +|--------|--------|-------|--------| +| Total `core/` size | 9.8M | 9.9M | +0.1M (1%) | +| DropdownMenu.js | 2,451 bytes | 2,854 bytes | +403 bytes (16%) | +| Source lines | 172 | 164 | -8 lines | + +The minimal bundle increase is expected since `@radix-ui/react-dropdown-menu` is a new package. However, Radix uses shared internal packages (`@radix-ui/react-primitive`, `@radix-ui/react-dismissable-layer`, etc.) that are already used by other Radix components in the project (Accordion, Select, Tooltip, etc.), so the actual incremental size is smaller. + +### 5. Test Results + +All existing tests pass: +``` +Test Files 1 passed (1) +Tests 3 passed (3) +``` + +Full test suite (189 tests) passes with no regressions. + +## Learnings + +### What Worked Well + +1. **Radix primitives map cleanly** - The compound component pattern (`Root`, `Trigger`, `Content`, `Item`) maps directly to the existing API structure +2. **Styling is flexible** - Radix uses `data-[state=open]` and `data-[highlighted]` attributes that work well with Tailwind +3. **No breaking changes needed** - The existing API is preserved 100% +4. **Portal-based rendering** - Menu renders in a portal, avoiding z-index issues + +### Minor Considerations + +1. **Animation classes** - Added Tailwind animate-in/out classes for smooth transitions (optional, can be removed if not desired) +2. **Focus management** - Added `onCloseAutoFocus` handler to prevent unwanted focus changes +3. **Role attribute** - The custom `role="menu"` on Content is preserved for consistency, though Radix manages ARIA automatically + +### What Would Need Attention in Production + +1. **Plain HTML children** - The third story example uses a plain `` tag inside Content. This works but doesn't get keyboard navigation highlighting. Consider wrapping in `DropdownMenu.Link` or documenting this limitation. + +2. **HeaderLinks usage** - The component is used in `HeaderLinks.tsx` with custom buttons inside Content. These will work but would benefit from being wrapped in Radix's `Item` for full keyboard support. + +## Recommendations + +1. **Proceed with migration** - The Radix implementation is production-ready +2. **Update consumer code** - Where custom content is used inside `DropdownMenu.Content`, wrap interactive elements in `RadixDropdownMenu.Item` for full accessibility +3. **Consider adding MenuItem** - Export a `DropdownMenu.Item` component for non-link menu items (buttons, etc.) +4. **Documentation** - Update component docs to highlight new keyboard navigation features + +## Time Taken + +- **Estimated**: 4-6 hours +- **Actual**: ~2 hours + +## Files Changed + +- `src/core/DropdownMenu.tsx` - Rewritten to use Radix primitives +- `src/core/DropdownMenu/DropdownMenu.stories.tsx` - Added
