I am trying to figure out how to implement something here. for some time, I used the Content Sidebar to show something across my blog posts. Now, I may need to have this kind of feature.... that would show different content on different posts. So, it wouldn't be "universal" like the content sidebar.
In the drag and drop options, I can't seem to harness something such as the banners to do just that.
Does anyone have a solution to suggest?
