I would like to use code folding with nested cell but I only manage to create individual cell. I would like my file to look more like a tree diagram. For example I would like to make a file similar to the outline below and if I collapse cell 1, I would like cell 1.1 and cell 1.1.1 to also collapse.
Thanks,

%% 1
%% 1.1
%% 1.1.1
%% 2
%% 2.1
%% 2.2
