title: Magento form validation of hidden values
body: <p>I have problem with default Magento form validation. I'm using accordion for checkout page, so when I submit form, some fields are hidden. I noticed all hidden fields are passing validation, even if they are empty (required-entry class used). Is there any way to force validation script to check all fields, not only visible ones?  </p>
  
  <p>Thanks in advance.</p>
