Hi all, I have a challenge and i could not find info anywhere on how to do this. I hope you can help!

Basically, i am writing a document that will be 100+ pages. This document will have up to 20 or more different headings and in every one of these headings, i will be breaking it down to 5/6 different subheadings. Each main heading will have the same 5/6 subheading names.

What i want to do is in the title page, i want to list those 5/6 subheadings as a dropdown list and when i select any one of them, the whole document will only display anything that was written under that subheading and every other subheading/text will disappear unless i selected to show all.

Is this even possible or have i amined too high?

Thanks for any help you can give!
Jack
