section-nav
The section-nav goes at the top of section pages when there is a manually-filled Nav links group in CUE. It’s a siple stack of an expander and icon row with small adjustments. On load, the section nav should be collapsed. If there isn’t a filled Nav links group in CUE it should render as a standard h1 with no caret by ommitting the expander class.
On mobile (600px), the section-nav headline reduces in size and the expandable list switches to a vertical stack with center alignment.
EXAMPLE
The section nav is included in the section deck and is better represented there.
