How to set up the secondary menu (All Departments)
Last update:
Tokyo’s secondary menu is designed to accommodate navigation menus with many items and make it easier for customers to browse product categories. While it can work with any menu hierarchy, it is particularly useful for stores with a large number of menu items or collections. To take advantage of this feature, create a nested navigation menu for your product categories.

Once the secondary menu is created, navigate to Online Store in your Shopify admin, select the Tokyo theme, and click Edit theme.
In the theme editor, select the Header section and scroll down to the Navigation settings. Under Secondary menu, select the menu you have just created as your online store’s secondary menu.

You can change the menu’s button text from the Secondary menu button label option (applies only to the Normal header layout). You can also add a Side item with an Image, Heading, a brief description (Text) and a Link to point to. This side item is displayed when the secondary menu is expanded, and is positioned below the first level menu items.
