I've been looking for it but I can't find a plugin for WordPress with this specific behavior. In any post, I want to put an excerpt or the total content of another post in a show/hide box, for the reader doesn't need to go to the entry. Example: Post1 I'm talking about THIS in this post. Post2 THIS content. When you click on THIS in the Post1, it opens a box (in any place), where you can read the content of Post2 (inline). Then you can hide the content again to read the rest of Post1 without navigating away of it. Thanks if you can help. (Note: I don't need a spoiler tag, because that hides content of the same post)
