Features Overview
- Add Dynamic Fields: Each added field is numbered and comes with a “Remove” button.
- Remove Fields: Clicking “Remove” deletes the associated field.
- jQuery Validation: Ensures required fields are filled (including dynamically added ones).
- Bootstrap Styling: Clean layout and responsive behavior.
