🔄 Workflow

For Form Creators

  1. Design → Use the visual builder or write JSON
  2. Export → Get JSON definition
  3. Import → Add to Django admin
  4. Activate → Mark form as active
  5. Share → Provide form URL to users

For End Users

  1. Visit → Open form URL
  2. Fill → Complete form fields
  3. Validate → See real-time validation
  4. Navigate → Progress through steps (if multi-step)
  5. Submit → Send form data

For Administrators

  1. Manage → View/edit forms in admin
  2. Monitor → Track form submissions
  3. Analyze → Export submission data
  4. Configure → Set validation rules
  5. Maintain → Update forms as needed

🚀 Deployment Considerations
