	// Commented out for now, to be revisited later as some people raised potential concerns with providing mobile-only features:
	// Allow content to be collapsible only on the mobile site which could be useful as mobile displays are smaller, so the threshold to wish to make something collapsible could be greater
	// to achieve this, change "mw-" to "MMC-" in all classes used. Do NOT use custom toggles as they won't be hidden on the desktop site.
	// let classes = ['collapsible','collapsed','collapsible-toggle','collapsible-content','collapsible-toggle-placeholder','collapsible-toggle-expanded'];
