The bar at the top holds two different kinds of thing, side by side, and you drag them into whatever order you want the menu to read in.
Named boxes are yours
Headings you created, with their names showing. They're your shop's own structure, so they always show what they're called — hunting for the right diamond to find "Trading Card Games" would be worse than the space it saves.
Diamonds are ours
Each ◆ is a link the platform provides because you have the feature switched on — Events, Gift Cards, Sell to Us, Menu, Blog, Pre-orders, Store League, Reserve Room/Table, Deck Import, Contact Us. They collapse to a marker at rest so the bar stays readable, showing you what is in the menu and in what order without a wall of words.
Point at one and it tells you what it is, with its On/Off switch:
On and Off
Turning a diamond off takes the link out of your menu without switching the feature off — your events still run, the page still works for anyone with the address, it just isn't in the bar. Useful when a feature isn't ready to show customers yet.
An off chip stays expanded, greyed, showing its name and its switch — because a hidden link collapsed to an anonymous diamond would be impossible to find again.
Order
Drag anything in the bar — headings and diamonds together — into the order you want. That order is the menu. Most shops put their games first and Contact last.
