I have downloaded many PDF files, some without bookmarks. Usually I add bookmarks for these PDF files manually, with Foxit PDF reader
But once I add the bookmark, the bookmark of the PDF file would unfold from top to bottom the next time I open it.
So how do I add/edit bookmarks of the PDF file without unfolding it? Is there a way to do this with Foxit reader, or will I have to use another program?
