I am a novice at this. I have the Site buttons across the main page. One of these is called About the Library. When you click on About the Library, the next page shows subcategories in the Left panel. This is what I want. But now I want to be able to edit each of the side submenus and have the content appear in the Center columns. What am I doing wrong? I can't seem to find the right Edit button for the submenus. I just get the Word Processor. Thank you.
