How to create a bookmark hierarchy in Acrobat Pro?

Question

System administration

Tell me how to create a bookmark hierarchy in Acrobat for a book in PDF format? For example, you open a book and in its table of contents you click on the section of interest and "move" to it. I do not know how to sound it correctly - like hyperlinks. I would be very grateful for your help...

Answer 1

About creating a hierarchy of bookmarks is written here . But first you need to create not a hierarchy, but the bookmarks themselves. This is also written in the same official manual , which for some reason everyone stubbornly does not want to read.
