+title: Replace planning category filter select with icon-aware dropdown
+area: ui

+
+## Problem
+
+The category filter in the planning tab uses a native HTML `<select>` element, which cannot render Lucide icons inline. After Phase 6 migrated all category icons from emoji to Lucide, this filter only shows category names without their icons — inconsistent with the rest of the app where category icons appear alongside names (CategoryPicker combobox, CategoryHeader, cards, etc.).
+
+This was documented as a deliberate deviation in 06-02-SUMMARY due to HTML `<select>` constraints.
+
+## Solution
+
+Replace the native `<select>` with a custom dropdown component (similar to CategoryPicker's combobox pattern) that renders `LucideIcon` + category name for each option. Reuse the existing popover/dropdown patterns from IconPicker or CategoryPicker.
