Important information regarding Pipeline 3.1
Shopify has introduced a new Nested Navigation system with full drag and drop menu creation. Previous versions of Pipeline can switch to the new Nested Navigation system in the Navigation Editor. Pipeline 3.1 only supports Shopify's new Nested Navigation. This means if you're updating from a previous version of Pipeline, your navigation will be forced to use Nested Navigation.
For that reason, you will need to create new sub-menu items within your Main Menu navigation. The first level of your Menu Menu will still be there, all sub-menu items will need to be created again. Previously, you were able to link other menus to create drop-down menus or Meganav. Now you'll need to create menu items within your Main Menu, then drag and drop under each parent menu to build sub-menus.
