Answer 1

Firstly, follow Energya's instruction:

pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
pip install jupyter_nbextensions_configurator
jupyter nbextensions_configurator enable --user

Second is the key: After opening jupiter notebook, click the Nbextension tab. Now Search "colla" from the searching tool provided by Nbextension(not by the web browser), then you will find something called "Collapsible Headings"

This is what you want!
