I have a standard Content.cshtml which is the default content type for my pages, I also have a custom Content-url-homepage.cshtml which is just for the homepage. This setup has worked well for me so far.
I now want to introduce a Two Column Layout (TwoColumnContent.cshtml) which is used as a Content.cshtml page for some of my pages, which I can include a Zone in.
The idea is to include Html Menu Widget in the Zone which I can use rules to create sub menus for the different areas.
The main question would be: How can I create a Content.cshtml page which will apply to multiple urls or Content pieces?
