Can a sidebar span two zones in omega 3 theme? I'm a bit of a newbee with Omega 3. I am having trouble arranging a grid which has a vertical sidebar span two zones. See the attached  diagram to understand the design requirements. I need to have a left sidebar and content block both appear under the header, and a right sidebar that spans both the the header and the content.  

I would like to know if it is possible to create such a grid within the standard Omega UI, or if not how can this be accomplished. 

Thanks!
No, with the way the HTML is built, it goes


zone-wrapper div (if used)

zone dov



region div




In your case, I would leave the Header zone empty (make sure the checkbox for forced rendering is off), and then move all of your regions to the Content zone.  In the grand scheme of things, there is nothing special about the Header zone.  I am looking at one of my sites now, and I left Header empty.

With the default templates, the Content zone also contains the Breadcrumb and Messages, so you may need to tweak this a bit to output the regions specifically to get these in the proper place.
