Hi Jim,
We can create email templates with zones setup the way you described. Would zones setup like this meet your needs?
The challenge we have is the need to give marketers a variety of layout options in one template. For example, one week, they may want to display product widgets in a 3-up layout, with some promotions in a 2-up layout. Another week, they way want to display a full width promotion, with products in a 2-up layout. Layout widgets would be great, but we can also solve this by providing a template with extra widget zones to provide a variety of layout options (this reminds me of Page Layouts in SharePoint :-) ). Here's an example of the zone's we might provide in one template. However, to make this work, we will make sure each section will have a zero height (invisible), if its zones are empty. If you need a lot of layout options, this "zone sandwich" solution might work for you too.
Thanks,
Mike
