# Task 2 - Add Cascading Location Filters

## Agent: main
## Status: Completed

## Summary
Added Division → District → Upazila → Union cascading location filters to House Rental, Shop Rental, and Medicine/Pharmacy modules using the comprehensive `bangladesh-locations.ts` data file.

## Files Modified
1. `src/components/modules/HouseRentalModule.tsx` - Added district/upazila/union to HouseFilters, cascading selects in filter Dialog, filter logic in useMemo
2. `src/components/modules/ShopRentalModule.tsx` - Same changes as HouseRentalModule
3. `src/components/modules/MedicineModule.tsx` - Added LocationFilters interface, filter button, filter Dialog, pharmacy location filtering

## Key Implementation Details
- Cascading behavior: parent change resets all children
- Division select uses placeholder when empty; District/Upazila/Union use `|| 'all'` pattern
- MedicineModule filters pharmacies by address string matching since products lack location fields
- All labels are bilingual (English/Bengali)

## Verification
- `bun run lint` passed
- Dev server compiles successfully
