## Testing Results

All components tested and verified:
- ✅ Base template exists and contains all required elements
- ✅ CSS file exists and contains all required styles
- ✅ JavaScript file exists and contains all required functions
- ✅ Django system check passes (no errors)
- ✅ File structure is correct
- ✅ Integration with existing templates maintained

---

## Usage Instructions

### For Template Developers:

To use the new accounting base template in future pages:

```django
{% extends 'accounting/base.html' %}

{% block accounting_content %}
    <!-- Your page content here -->
{% endblock %}

{% block accounting_extra_css %}
    <!-- Page-specific CSS -->
{% endblock %}

{% block accounting_extra_js %}
    <!-- Page-specific JavaScript -->
{% endblock %}
```

The template automatically includes:
- accounting/css/accounting.css
- Navigation menu
- Breadcrumbs (set via context variable `breadcrumbs`)

### Setting Breadcrumbs:

In your view, add to context:

```python
context['breadcrumbs'] = [
    {'title': 'Accounts', 'url': reverse('accounting:account_list')},
    {'title': 'Account Details', 'url': None},  # Current page (no link)
]
```

### Using JavaScript Functions:

```javascript
// Calculate current totals
const totals = calculateTotals();
console.log(totals.isBalanced);

// Add a line programmatically
addLineItem();

// Remove specific line
removeLineItem(2);  // Remove line at index 2

// Initialize autocomplete on new select
const accountSelect = document.querySelector('select[name="account"]');
initAccountAutocomplete(accountSelect);
```

2. **Refactor Existing Templates**
   - Update existing templates to extend `accounting/base.html`
   - Add breadcrumb context to views

3. **Select2 Integration**
   - Replace native autocomplete with Select2 library
   - Enhanced search and filtering capabilities

4. **Real-time Validation**
