Sidebar not compatible

[heinermann]

After setting up with the provided documents, and using GENERATE_TREEVIEW = YES, the resulting page unexpectedly looks like the following.

With GENERATE_TREEVIEW = NO, it appears as I would expect.

The generation did not use any additional external styles/formatting. It would be difficult to navigate this particular documentation without some sort of side bar.

Currently the sidebar is not supported, I think I made of note of it in the readme. With the current fixed width layout it's not clear to me how a sidebar would work/layout with respect to the rest of the page. I'm open to suggestions, maybe supporting fluid and fixed width with a compile time flag?
