Reordering Menu Items
To reorder menu items, simply hover over the item you’d like to move until you see the "move" cursor appear then click and drag the item to the desired location within the menu. If it should be a top level element (meaning not nested under a parent element in a drop down menu), make sure the item is fully aligned to the left with the other top level items. If it is indented slightly, Wordpress will interpret this as a nested item.
