Content - Menu Wrapper Start
This block type denotes the beginning of a group of navigation menu items. It’s primary use is to keep the adjacent group of menu items aligned properly with each other in a column, which can be configured here.
Likewise there’s an end wrapper to close off the group of menu items. For more information on how to build your navigation menus, check out the Navigation Menu chapter.

The settings here apply to all adjacent menu items until it reaches an “End Wrapper”.
