Native basis

A <div>: the Breadcrumb component (with a home icon), a back link to the parent shown only below 30rem (container query), and the page title. The collapsed variant puts the middle levels in a popover behind a "…" button.

Built from

Data attributes

data-variant="collapsed".

§Default

The Breadcrumb component (the home icon is named) above the title. Below 30rem of width - resize the preview to Mobile - a container query swaps the trail for "← Billing".

§Collapsed

data-variant='collapsed': deep trails keep the first and last levels; the middle ones open from "…" in a popover anchored to it.
