Menus

• Primary menu — The main navigation — assigning it, how deep it can go, and what happens when it runs out of room.
• Dropdowns and sub-menus — How a sub-menu opens on the desktop bar, what it looks like, and why the mobile drawer does it differently.
• Mobile menu — The drawer behind the hamburger — what it contains, how it behaves, and what it does with JavaScript switched off.
• Social menu — The menu location that feeds the brand-icon rows, and the three places it can appear.
• Footer menu — The flat row of links beside the copyright line.
