I use collapsible headings nbextension in jupyter notebook. When the notebook is converted to an html using jupyter nbconvert --html mynotebook.ipynb, the headings are no longer collapsible in the resulting html. Is it possible to apply this nbextension with nbconvert?
I wrote this jquery script by myself. Just add this as a raw nbconvert script in your notebook. The collapsible headings nbextension is not supported in html yet. See the discussion on their repo.
