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.
