Password Confirmation

Add this class to both password fields to ensure they match.
Submit Button Loader
class="y-has-loader"
Add this class to the submit button to enable the automatic loading animation upon valid form submission.
Useful JS API
// Manual validation check
let isValid = y_validate_form( element );
// Add custom error message
y_add_error_msg( field, 'Your custom message' );
// Remove error message
y_remove_error_msg( field );
// Blur callback function
function y_blur_after_validate( field ) { ... }
Smart AJAX Loader
// Automatically stops the loader when your AJAX request (Fetch or XHR) is completed.
// Optional manual override:
y_hide_loader( form_element );
Requires adding the y-has-loader class to the submit button. Prevents double-submissions automatically.
