How do I make a complex grid layout with the Omega theme where regions can be embedded in regions? I included an image of how I want the page layout to be set. Right now I'm thinking that I will use the CSS property in the Views UI to manually set the grid-[columns] and alpha or omega properties of the Views block. Is there a better way of doing this so the code is in a logical place and not a hack?
For something like this, I will simply use the Block Class module and for the blocks I'm placing inside a region, add a grid-X and alpha/omega appropriate classes as needed.
I've never found the reason (even in really advanced layouts/designs/grids) to do anything more than that...
Use the views_column_class module (http://drupal.org/project/views_column_class).
This lets you add alpha, omega and other settings to views so that they don't break your grid.
