## 🎯 Implementation Guidelines

### Form Design Principles:
1. **Mirror Paper Forms** - Layout should match original clinical forms exactly
2. **Crispy Forms** - Use consistent layout with Fieldsets, Rows, Columns
3. **Bilingual Labels** - All labels wrapped in `_()` for translation
4. **Validation** - Custom clean methods for business rules
5. **Auto-calculations** - JavaScript for BMI, totals, percentages
6. **Inline Formsets** - For one-to-many relationships (medications, behaviors, targets)
7. **Conditional Display** - Show/hide fields based on selections
8. **Help Text** - Clear instructions from original forms
9. **Search Forms** - Consistent pattern with tenant filtering

### Technical Patterns:

#### Inline Formset Pattern:
```python
from django.forms import inlineformset_factory

MedicationPlanFormSet = inlineformset_factory(
    MedicalConsultation,
    MedicationPlan,
    fields=['drug_name', 'dose', 'frequency', ...],
    extra=3,
    can_delete=True,
    min_num=1,
    validate_min=True,
)
```

#### Crispy Forms Layout Pattern:
```python
self.helper.layout = Layout(
    Fieldset(
        _('Section Title'),
        Row(
            Column('field1', css_class='form-group col-md-6 mb-0'),
            Column('field2', css_class='form-group col-md-6 mb-0'),
            css_class='form-row'
        ),
    ),
    Submit('submit', _('Save'), css_class='btn btn-primary')
)
```

#### Validation Pattern:
```python
def clean(self):
    cleaned_data = super().clean()
    field1 = cleaned_data.get('field1')
    field2 = cleaned_data.get('field2')
    
    if field1 and field2:
        # Business rule validation
        if some_condition:
            raise forms.ValidationError(_('Error message'))
    
    return cleaned_data
```

## 📈 Progress Tracking

**Completed:** 4 of 9 apps (44%)
**Remaining:** 5 apps (56%)

**Estimated Time:**
- Medical forms: 4-6 hours (complex, multiple sections)
- ABA forms: 2-3 hours (inline formsets)
- OT forms: 3-4 hours (target scoring, inline formsets)
- SLP forms: 6-8 hours (most complex, variant-specific, SOAP format)
- Referrals forms: 1-2 hours (simple)

**Total Remaining:** 16-23 hours

## 🚀 Next Steps

1. Create `medical/forms.py` with all 3 forms
2. Create `aba/forms.py` with 3 forms
3. Create `ot/forms.py` with 4 forms
4. Create `slp/forms.py` with 5 forms
5. Create `referrals/forms.py` with 2 forms
6. Test all forms with validation
7. Update PROJECT_STATUS.md
8. Move to Phase 3 (Views)

## 💡 Key Considerations

- **Clinical Accuracy:** Forms must match paper forms exactly
- **User Experience:** Intuitive flow, clear labels, helpful validation
- **Performance:** Efficient queries for dropdowns, lazy loading where needed
- **Accessibility:** Proper labels, ARIA attributes, keyboard navigation
- **Mobile Responsive:** Bootstrap grid system ensures mobile compatibility
- **Bilingual:** All text wrapped in translation functions
- **Audit Trail:** Forms integrate with simple_history for tracking changes
