title: Remove woocommerce default checkout form
body: <p>Since I'm not very skilled in php, I've tried to remove thru css the woocommerce default form (so I could use my custom fields).
  The problem is that woocommerce is still givin me error at the end of checkout because some fileds are required in the default form.</p>
  
  <p>I've already added this code to ignore default checkout form, added an addon (N-media), form looks perfect but on checkout does nothin.</p>
  
  <pre><code>function custom_override_checkout_fields( $fields ) {
  unset($fields['billing']['billing_first_name']);
  unset($fields['billing']['billing_last_name']);
  unset($fields['billing']['billing_company']);
  unset($fields['billing']['billing_address_1']);
  unset($fields['billing']['billing_address_2']);
  unset($fields['billing']['billing_city']);
  unset($fields['billing']['billing_postcode']);
  unset($fields['billing']['billing_country']);
  unset($fields['billing']['billing_state']);
  unset($fields['billing']['billing_phone']);
  unset($fields['order']['order_comments']);
  unset($fields['billing']['billing_address_2']);
  unset($fields['billing']['billing_postcode']);
  unset($fields['billing']['billing_company']);
  unset($fields['billing']['billing_last_name']);
  unset($fields['billing']['billing_email']);
  unset($fields['billing']['billing_city']);
  return $fields;
  </code></pre>
  
  <p>}</p>
  
  <p>I wish to remove it for good and keep on using my custom form.</p>
  
  <p>Thank you in advice.</p>
