Single-page documentation (\wout toctree)

[chrisjsewell]

In https://sphinx-panels.readthedocs.io I have some simple documentation, that is currently all included in the index.rst. This works fine for the sphinx_rtd_theme, but if I just change the theme to pydata_sphinx_theme I get:

Theme error:
An error happened in rendering the page index.
Reason: AttributeError("'NoneType' object has no attribute 'children'")
make: *** [html] Error 2

At a minimum, the error handling here should be more informative, if there is not toctree data.

If I try adding a self-referencing toctree in index.rst, e.g.

.. toctree::
    
    index

It builds, but I get self-referencing warnings (see sphinx-doc/sphinx#7410), so that's not ideal.

This would also be relevant to #90 (cc'ing @choldgraf )

I think that I've fixed this one in sphinx-book-theme since it has a single page version that works pretty well. I can try to figure out where that fix was and upstream it

Any movment on this one ? or are we simply relying on sphinx-book-theme for single page documentation ?

We had cleaned up our build code a while back, and I suspect that this issue was resolved then. I just tried re-building these docs after deleting the toctrees from our index.rst file, and it built fine, so I think we can close this!
