I saw a PDF document that had a button on it called Navigation.
When you click on the button, a small document (think it was also a pdf) popped up over the top right of the PDF page which had navigation links to other PDF documents.
I didn't see how it was done but I would like to replicate it.
Can you share the file?
Hi Bernd, no sorry that's my problem. I just saw it working but have no contact with the owner or possessor of the document. 😞
Without seeing the file it's very hard to say for sure. My guess is they used some graphic elements and form fields to a certain part of the page, hid them and them made them visible when the button was clicked. It might even be on a separate layer.
