# Checklist Item Creation Feature - Implementation Summary

## Overview
Successfully implemented the "Add Checklist Item" functionality for the Acknowledgement Section management page.

## Problem Identified
The checklist list page (`templates/accounts/onboarding/checklist_list.html`) was missing:
1. A modal form to create new checklist items
2. JavaScript functionality to handle form submission
3. Integration with the existing API endpoint
4. Dropdowns for roles and linked content in the form

## Solution Implemented

### 1. Template Updates (`templates/accounts/onboarding/checklist_list.html`)

#### Added Components:
- **"Add Checklist Item" Button**: Primary action button to open the modal
- **Bootstrap Modal Form**: Complete modal with all required fields
- **JavaScript Functionality**: 
  - `saveChecklistItem()` function to handle form submission
  - Form validation
  - AJAX integration with API endpoint
  - Success/error handling with alerts
  - Modal reset on close

#### Form Fields:
1. **Code** (required): Unique identifier (e.g., CLINIC_P1)
2. **Role**: Dropdown with options (All Roles, PX Admin, Hospital Admin, etc.)
3. **Linked Content**: Dropdown to associate with existing content sections
4. **Text (English)** (required): Main text for the checklist item
5. **Text (Arabic)**: Arabic translation
6. **Description (English)**: Additional details
7. **Description (Arabic)**: Arabic translation
8. **Required**: Toggle switch (default: checked)
9. **Active**: Toggle switch (default: checked)
10. **Display Order**: Numeric order field (default: 0)

### 2. View Updates (`apps/accounts/ui_views.py`)

#### Modified Function: `acknowledgement_checklist_list()`

**Added:**
```python
# Get all content for the modal dropdown
content_list = AcknowledgementContent.objects.filter(
    is_active=True
).order_by('role', 'order')

context = {
    'page_title': 'Acknowledgement Checklist Items',
    'checklist_items': checklist_items,
    'content_list': content_list,  # NEW
}
```

This ensures the content dropdown in the modal is populated with available content sections.

### 3. Integration Details

#### API Endpoint:
- **URL**: `/api/accounts/onboarding/checklist/`
- **Method**: POST
- **Content-Type**: application/json
- **Authentication**: Required (CSRF token)
- **Permissions**: PX Admin only

#### JavaScript Flow:
1. User clicks "Add Checklist Item" button
2. Bootstrap modal opens with empty form
3. User fills in form fields
4. JavaScript validates required fields
5. On "Save", function prepares JSON data
6. AJAX POST request to API endpoint
7. On success: Show success alert, close modal, reload page
8. On error: Display error message in modal
9. Modal reset when closed
