Sorry this isn’t really a support question but I just don’t know how you are supposed to set up a sub menu. By sub menu I mean when you hover over the menu and more options drop down. Thanks for helping.
Once an item is added to a menu, those menu items can be rearranged. Placing the mouse cursor over the menu item title, when the mouse cursor changes to 4-arrows, hold the left-mouse button down, drag the module to where you want to place it, then release the mouse button (this is called drag-and-drop). Remember you can drag a menu item slightly to the right of the menu item above it to create a hierarchy (parent/child) relationship in the menu.
