There's a problem with my navbox and I'm not sure how to fix it. It doesn't extend across the page like it should. I copied the navbox coding from the Super Mario Wiki to start off with (I was given permission to do so), but it's not quite working right and I don't know what I'm doing.... If I get rid of the "collaspe" options, it'll be the correct page width, but the contents will be stuck open.

Can someone provide me with the proper coding with the template? I looked at the given navbox template as well, but that isn't helping much, either...

Template in question found here.
