A pull-down menu to help save space on the sidebar

There, I just succeeded at fitting in a drop-down menu, as it's actually called, on the side for all the sections. That helps to save space and fit all external links into a nice compact space, and will probably also help make it easier to load the pages too. One thing I can't seem to figure out though is how to control the exact length so that it doesn't look like it's going halfway off the screen, even though it does look like I added the correct codings when I preview it. Oh well, what matters for now is that I succeeded in working out something I'd wanted to experiment with for some time now, and to make everything easier to handle and to load onto the screen! Perfect.
