# Phase 6 Plan 2: Category Icon UI Components Summary

**IconPicker component with search/group tabs and all category create/edit/display flows migrated from emoji to Lucide icons**

## Performance

- **Duration:** 5 min
- **Started:** 2026-03-15T16:53:11Z
- **Completed:** 2026-03-15T16:58:04Z
- **Tasks:** 2
- **Files modified:** 9

## Accomplishments
- Created IconPicker component with portal popover, search filtering, 8 group tabs, and 6-column icon grid
- Replaced EmojiPicker with IconPicker in CategoryPicker, CategoryHeader, and OnboardingWizard
- Updated CategoryPicker to show LucideIcon prefix in input and dropdown list items
- Build succeeds with no TypeScript errors

## Task Commits

Each task was committed atomically:

1. **Task 1: Create IconPicker component** - `59d1c89` (feat)
2. **Task 2: Update CategoryPicker, CategoryHeader, OnboardingWizard, and CreateThreadModal** - `570bcea` (feat)

## Files Created/Modified
- `src/client/components/IconPicker.tsx` - New portal-based Lucide icon picker with search and group tabs
- `src/client/components/CategoryPicker.tsx` - Uses IconPicker for inline create, LucideIcon for display
- `src/client/components/CategoryHeader.tsx` - LucideIcon in view mode, IconPicker in edit mode
- `src/client/components/OnboardingWizard.tsx` - IconPicker for category creation step
- `src/client/components/CreateThreadModal.tsx` - Removed emoji from category select options
- `src/client/hooks/useCategories.ts` - Fixed emoji -> icon in useUpdateCategory type
- `src/client/routes/collection/index.tsx` - Fixed categoryEmoji -> categoryIcon references
- `src/client/routes/setups/$setupId.tsx` - Fixed categoryEmoji -> categoryIcon references
- `src/client/routes/threads/$threadId.tsx` - Fixed categoryEmoji -> categoryIcon reference

## Decisions Made
- Native HTML `<select>` elements cannot render React components, so category select dropdowns show name only (no icon prefix)
- IconPicker uses 6-column grid instead of EmojiPicker's 8-column for better visibility of icons at 20px

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Fixed categoryEmoji -> categoryIcon in collection and setup routes**
- **Found during:** Task 2
- **Issue:** Routes passed `emoji={categoryEmoji}` to CategoryHeader and used `item.categoryEmoji` which no longer exists after Plan 01 renamed the field
- **Fix:** Updated all `categoryEmoji` references to `categoryIcon` and `emoji=` prop to `icon=` in collection/index.tsx, setups/$setupId.tsx, and threads/$threadId.tsx
- **Files modified:** src/client/routes/collection/index.tsx, src/client/routes/setups/$setupId.tsx, src/client/routes/threads/$threadId.tsx
- **Verification:** Build succeeds
- **Committed in:** 570bcea (Task 2 commit)

**2. [Rule 3 - Blocking] Fixed useUpdateCategory hook type from emoji to icon**
- **Found during:** Task 2
- **Issue:** useUpdateCategory mutationFn type still had `emoji?: string` instead of `icon?: string`
- **Fix:** Changed type to `icon?: string`
- **Files modified:** src/client/hooks/useCategories.ts
- **Verification:** Build succeeds
- **Committed in:** 570bcea (Task 2 commit)

---

**Total deviations:** 2 auto-fixed (2 blocking)
**Impact on plan:** Both fixes were necessary for build to pass after Plan 01 renamed emoji to icon. No scope creep.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- IconPicker and all category create/edit components complete
- EmojiPicker.tsx and emojiData.ts can be removed in Plan 03 (cleanup)
- Some display components (ItemCard, ThreadCard, etc.) were already updated in Plan 01
