Dropdown Menu

[Connie]

yes, many users managed to do that

I think it is a misunderstanding:

you have pages and subpages
the pages are shown at the top and the subpages of the relevant pages are shown in the sitebar
what is wrong?

Either you want a dropdown (subpages are shown below the menu-items when you hover over these items) or you want the subpages in the sitebar or you want both, than you have to add the CSS!

1)
if you want to have that dropdown menu, you must add the relevant CSS to the css-file "style.css", I do not see these declaration in your page's CSS at all, so you will not see the submenus

2)
if you want to have a correct submenu in the sitebar, you must include the code for that in <ul> </ul>, which I see not in your code, thus you get errors

one hint: the titles of your pages are too long for the headers' font-size
