+# ValidationStepNew Implementation Status
+
+## Overview
+
+This document outlines the current status of the ValidationStepNew implementation, a refactored version of the original ValidationStep component. The goal is to create a more maintainable, modular component that preserves all functionality of the original while eliminating technical debt and implementing modern UI patterns.
+
+## Design Principles
+
+Based on the user's preferences, we're following these core design principles:
+
+1. **Automatic Validation**
+   - ✅ Validation runs automatically on data load
+   - ✅ No explicit "validate all" button needed
+   - ✅ Fields validate on blur when user clicks away
+   - ✅ Immediate visual feedback for validation errors
+
+2. **Modern UI Patterns**
+   - ✅ Command/popover components for selects and multi-selects
+   - ✅ Consistent field outlines and borders even when not in focus
+   - ✅ Badge pattern for multi-select field items
+   - ✅ Visual indicators for errors with appropriate styling
+
+3. **Reduced Complexity**
+   - ✅ Removed unnecessary UI elements like "validate all" button
+   - ✅ Eliminated redundant toast notifications
+   - ✅ Simplified component hierarchy
+   - ✅ Fixed root causes rather than adding special cases
+
+4. **Consistent Behavior**
+   - ✅ Fields close when clicking away
+   - ✅ All inputs follow the same editing pattern
+   - ✅ Error handling is consistent across field types
+   - ✅ Multi-select fields allow selecting multiple items
+
+## Completed Components
+
+### Core Structure
+- ✅ Main component structure
+- ✅ Directory organization
+- ✅ TypeScript interfaces
+- ✅ Props definition and passing
+
+### State Management
+- ✅ `useValidationState` hook for centralized state
+- ✅ Data validation logic
+- ✅ Integration with rowHook and tableHook
+- ✅ Error tracking and management
+- ✅ Row selection
+- ✅ Automatic validation on data load
+
+### UI Components
+- ✅ ValidationContainer with appropriate layout
+- ✅ ValidationTable with shadcn UI components
+- ✅ ValidationCell factory component
+- ✅ Row select/deselect functionality
+- ✅ Error display and indicators
+- ✅ Selection action bar
+
+### Cell Components
+- ✅ InputCell with price and multiline support
+- ✅ MultiInputCell with separator configuration
+- ✅ SelectCell using command/popover pattern
+- ✅ CheckboxCell with boolean mapping
+- ✅ Consistent styling across all field types
+- ✅ Proper edit/view state management

+
+## Pending Tasks
+
+### Enhanced Validation
+- ⏳ AI validation system
+- ⏳ Custom validation hooks
+- ⏳ Enhanced UPC validation with API integration
+- ⏳ Validation visualizations
+
+### Advanced UI Features
+- ⏳ Table virtualization for performance
+- ⏳ Drag-and-drop reordering
+- ⏳ Bulk operations (copy down, fill all, etc.)
+- ⏳ Keyboard navigation improvements
+- ⏳ Template dialogs and management UI
+
+### Special Features
+- ⏳ Image preview integration
+- ⏳ SKU generation system
+- ⏳ Item number generation
+- ⏳ Dependent dropdown values
+
+### Testing
+- ⏳ Unit tests for utility functions
+- ⏳ Component tests
+- ⏳ Integration tests
+- ⏳ Performance benchmarks
+
+## Known Issues
+
+1. TypeScript error for `validationDisabled` property in ValidationCell.tsx
+2. Some type casting is needed due to complex generic types
+3. Need to address edge cases for multi-select fields validation
+4. Proper error handling for API calls needs implementation
+
+## Next Steps
+
+1. Fix TypeScript errors in ValidationCell and related components
+2. Complete template management functionality
+3. Implement UPC validation with API integration
+4. Make multi-select field validation more robust
+5. Add comprehensive tests
+
+## Performance Improvements
+
+We've already implemented several performance optimizations:
+
+1. ✅ More efficient state updates by removing unnecessary re-renders
+2. ✅ Better error handling to prevent cascading validations
+3. ✅ Improved component isolation to prevent unnecessary re-renders
+4. ✅ Automatic validation that doesn't block the UI
+
+Additional planned improvements:
+
+1. Virtualized table rendering for large datasets
+2. Memoization of expensive calculations 
+3. Optimized state updates to minimize re-renders
+4. Batched API calls for validation
