In a support thread titled ‘Topic list on the right side,’ daemon inquires about the right-side heading list visible in certain Discourse topics, wondering if it’s automatic or requires configuration. Steven clarifies that this is not a topic list but a Table of Contents (ToC) generated by the ‘Disco TOC’ theme component, linking to its documentation here. daemon thanks Steven and admits they didn’t know the term ‘ToC,’ then follows up asking where to find the ‘Blur Spoiler’ theme component, referencing a screenshot from the Disco TOC topic. After searching, daemon later confirms they found it. The discussion centers on theme components for enhancing post navigation and content presentation in Discourse, with emphasis on Disco TOC’s automatic ToC generation and a brief side quest for Blur Spoiler.
Hi at all!
In the topic Embed Discourse comments on another website via Javascript I saw this.
While reading the first post, on the right side is a list of headings. Only when you come to the second post you see again the list with the date when a post was written.
How to do it? Or does this happen automatically as soon as you insert a headline in the post?
This is not a topic list but a summary of this guide. It uses Disco TOC a great theme component
Sorry I didn’t know the name for this “topic list”. 
But yes you’re right, it’s a toc.
And many thanks for the link! 
That is what I was looking for.
EDIT:
In the topic for the theme component I saw this screenshot.
So my question is, where can I found the plugin/theme component “Blur Spoiler”?
I have looked in the whole forum but I can’t find it.
EDIT2:
found it!
