InfoVisit Shopify’s help centre for an extensive guide on setting up menus and links.
Menus can be configured to display in two ways – as a single dropdown or in multi-columns with nested menu items.
Single dropdown menu
To create a single dropdown menu, click the title of the menu that you would like to add a dropdown menu to. In most cases, this is called Main Menu unless it has been renamed to something else.
Next, you will need to add ‘child’ items to include in the new drop-down.
Click Add menu item, enter a name of the menu item and select a destination for the link.
Click and drag the menu items to nest below the ‘parent’ item.
Click Save menu.
