<script>
$(document).ready(function() {
    // Hide the additional fields initially
    $('.additional-fields').hide();
    
    // When the user types in the email input
    $('#email-input').on('input', function() {
        var email = $(this).val();
        // You can add your email validation logic here
        
        // If email is valid, reveal the additional fields
        if (isValidEmail(email)) {
            $('.additional-fields').slideDown();
        }
    });
    
    // Function to validate email (you can replace this with your own validation logic)
    function isValidEmail(email) {
        // Your validation logic here
        return /\S+@\S+\.\S+/.test(email);
    }
});
