Collapsible TOC?

[wez]

The TOC for WezTerm's docs is pretty big and would be improved by making the levels able to collapse through some javascript stuff so that you could click to expand/collapse the different sections and make it easier to get an overview.

I know enough about web dev to know that this shouldn't be tremendously difficult, while simultaneously knowing that I don't know enough to make something appropriately portable on my own :-)

Has anyone thrown together an example of this sort of thing, and/or considered integrating it into the baseline mdbook?

The fold options can be used to collapse parts of the summary. https://rustc-dev-guide.rust-lang.org/ is a demonstration of what it looks like.

Thanks! Was that relatively recently introduced?
May I suggest adding the word "collapse" in those docs as a kind of SEO to aid people like me that didn't think of it as folding?

It's been around for a few years. Feel free to open a PR to update the docs (source is at https://github.com/rust-lang/mdBook/blob/master/guide/src/format/configuration/renderers.md).
