codefolding on google colab

Question

I've tried enabling code folding on google colab with

!jupyter nbextension enable codefolding/main

based on this answer and using the command line found here

However the response on colab is

Enabling notebook extension codefolding/main...
      - Validating: problems found:
        - require?  X codefolding/main

Is it possible to do codefolding on colab?

Answer 1

It seems you didn't perform the second step of the installation process after !pip install jupyter_contrib_nbextensions. Install javascript and css files also.

!jupyter contrib nbextension install --user

This step copies the nbextensions' javascript and css files into the jupyter server's search directory, and edits some jupyter config files.
