title: Multiple Groupings within a Content Query Web Part
body: <p>Does anyone know of a way to do multiple groupings on a content query web part. I have been able to customeize everything else, but the sub groupings issue has me.</p>
  
  <p>What I need to do is, first group the list by column1, then within that grouping group on column2.</p>
  
  <p>Any help would be great. Thanks</p>
