Hi, I am looking for a plugin or code snippet I can use to tag specific parts of a post with tags or categories. Basically I'd like viewers who are using the categories to see the portions of the post which directly relate to the category they have clicked on (selected by me). The relevant post area would be either highlighted, or marked with a box, or something around the texts margins. Is there anything like this? could you recommend some code I could use to implement this functionality?
