Make a nav: subcategory always collapsed

[couleurm]

Hello, is it possible to indicate for a section of mkdocs.yml:nav to always be collapsed while keeping others opened?

e.g this Linux category:

firefox_Ala7q1ms0M.mp4

Hello,
I don't think so. Once you enable the navigation.expand feature every navigation section will get expanded.
However, you could disable that feature, and later add your own code to manage navigation expansion.

We do so on the Gothic Modding Community Page:
https://github.com/Gothic-Modding-Community/gmc/blob/dev/overrides/assets/javascripts/extra.js#L151-L196
However, I'm not sure if the code is the best, as it changes the checked state of the input elements, and perhaps this should be limited to only the active navigation element 🤔

mkdocs-material/src/templates/assets/javascripts/patches/indeterminate/index.ts

Lines 60 to 85 in d363f90

	export function patchIndeterminate(
	{ document$, tablet$ }: PatchOptions
	): void {
	document$
	.pipe(
	switchMap(() => getElements<HTMLInputElement>(
	".md-toggle--indeterminate"
	)),
	tap(el => {
	el.indeterminate = true
	el.checked = false
	}),
	mergeMap(el => fromEvent(el, "change")
	.pipe(
	takeWhile(() => el.classList.contains("md-toggle--indeterminate")),
	map(() => el)
	)
	),
	withLatestFrom(tablet$)
	)
	.subscribe(([el, tablet]) => {
	el.classList.remove("md-toggle--indeterminate")
	if (tablet)
	el.checked = false
	})
	}

The navigation.expand feature changes the indeterminate attribute as fas as I understand.
