title: Sitecore 6 WFFM: How to hide fields?
body: <p>In Web Forms for Marketers, I have a few fields that I am using to pass values to the pipeline processors and to append CSS code to the form. </p>
  
  <p>I don't want these fields to appear on the form. How can I mark a field to be invisible? Right now I am doing this via CSS, but I am quite sure there must be a better way to do so. </p>
  
  <p>Thanks! </p>
