Add a toctree to sidebar for tabbed content

[ma-sadeghi]

Consider the following snippet:

##########
Generators
##########

.. tab-set::

   .. tab-item:: Tutorials

      .. toctree::
         :maxdepth: 2
         :glob:

         tutorials/*

   .. tab-item:: Reference

      .. toctree::
         :maxdepth: 2
         :glob:

         reference/*

The folders reference and tutorials each contain a set of Jupyter notebooks, which are nicely tabulated using the above snippet, however, the toctree in the sidebar doesn't have the "tabbed" structure, instead all of notebooks are listed under "Generators".

My question is: is there a way to make the toctree in the sidebar to be hierarchical, meaning that Generators drop down would show two items: Tutorials and Reference, each having their own drop down. Thank you so much!
