🐛 version switcher in sidebar

[enryH]

Hey!

Thanks for the grate template. It might be an issue related to #1629. If I follow the instructions as described here to add the switcher to the sidebar, I ran into the following error:

sphinx.errors.ThemeError: An error happened in rendering the page developer-guide/adding-module.
Reason: UndefinedError("'super' is undefined")

I added the a _template_path to the conf.py and added to the file _templates/sidebar-nav-bs.html as specifed in the _templates folder.

I have the switcher no in the navigation bar and that works fine
