Hello! I'm currently creating a document on Atlassian Confluence, and i'm trying to create a box similiar to the one as shown in the picture.
The purpose of the box is for me to put in a content page, so that the person reading my document can easily refer to each section by clicking on the text in the box. And this box will follow the person reading my document as he scrolls.
I believe this has something to do with macros, and thus i'd like to know what the box is called so that i can google more on how to create it
