How to make navigate sidebar and toc section collapsible?

[Soyoon-Choi]

I've read #3428 , but it seems like it is stopped to develope that feature. How do I customize the navigation sidebar and the table of contents section collapsible? I think it's possible by modifying the html file in partials, but I'd like to know how to do it specifically.

We are still considering this change, but we are currently working on bigger things in the background. It will eventually be implemented, but we'll need some more time, as we're a very small team. Maybe another community member can share a solution that you can use right now before we ship native support ☺️
