Dropdown submenus
Use Add submenu under a menu item to add links that open in a dropdown. Submenus are one level deep: a submenu item cannot contain another submenu.
They are useful when you have enough pages that the main navigation would otherwise become crowded. For example, a Services item can contain links to individual service pages.
If the parent menu item also has its own destination, it stays clickable while a separate arrow opens the submenu. That way visitors can still reach the main Services overview page. The destination is optional, though: leave it empty and the item just opens its submenu, so you don't need an overview page for it.
Menus on multilingual websites
Menu labels are translated by language. Choose the language above the menu, then edit the labels and links for that version. A menu item's destination can differ by language too: give it another address in one language and it leads there in that language, or leave it empty to use the same destination everywhere. A page of your own picked from the list already opens in the visitor's language, so it needs no separate link. Each item can also be set visible only in selected languages, so a Hungarian-only page does not appear in the English menu.
