Using a Twenty Eleven child theme that supports 2 custom post types. Would like the "blog" page to have a sidebar that shows categories and tags. The 2 custom post pages have their own taxonomies and do not need a sidebar with the blog page's categories and tags.
In Theme Options' default layout, if I select One-column, no sidebar, then the blog page obviously has no sidebar; if I select Content on left, then the custom post pages have the sidebar.
What mods do I need to do to have a sidebar for the blog page and no sidebars for the custom post pages and the other static pages?
