    The sidebar Table of Contents can now be set to the full ``toc`` directive,
    or remain as the ``toctree`` directive.

    This can be set by setting ``"sidebar_mode"`` to ``"toc"`` in the
    ``html_theme_options`` option in ``conf.py``.

    For example:

    ::

      html_theme_options = {
           "sidebar_mode": "toc",
        }
