How can I make the content list of a PDF expanded by default?
I am writing a thesis using LaTeX and everything is just fine. However, as my project includes three different parts for which I use the command \part{}. I notice that when I open the PDF file and check the contents on the left, I need to click to open the part and see the contents inside.
Is there a way of telling the PDF file to open with all the menu opened by itself?
