{{#freestyle-usage "gutter-nav" title="Gutter Menu"}}
Since there will only ever be one gutter menu in the UI, it makes sense to express the menu as a singleton component. This is what that singleton component looks like.
Note: Normally the gutter menu is rendered within a page layout and is fixed position. The columns shown in this example are only to imitate the actual width without applying fixed positioning.
