A submenu (drop down menu) allows you to nest up to 15 submenu items under a single menu item.
A submenu creates a new top-level menu item under which you can then add more submenu items. Existing menu items can’t be used as submenus, so you’ll have to set up new ones.
To create a submenu, use the + submenu button at the bottom of the menu editor. Once you’ve named your submenu, you can proceed to add links by clicking on the Add button directly under your newly created submenu.
You can reorder submenu items just like any other menu - simply drag and drop the items into the desired order. Using separators is also possible.
