How do I set PDF file so that you can see PDF itself and bookmark links together?

[KAYOKO ISHINO]

I need information that tells me how to create PDF file with bookmark links. I mean, now I could put bookmark links on my PDF file but it doesn't show the bookmarks when I open the PDF file.
I have to click the bookmark button when I want to see the bookmarks I made.
Could you please give me the information if you know how to do. Thank you.
