because you have looked at the english part not on the italian page (all pictures was from italian page)..booth pags have a menu, i've used the standard menu module, and created menu voices for booth language.
anyway the same problem i've on my website is also present in your demo site, if you look on the demo site
with a mobile the menu will be cutted as you can see in the picture below.
Jep, the menu is cut off if you use more than a certain amount of menu items.
But you can scroll up and down the menu with your thumb to select your menu item(s). If you select one the new page will be loaded with a hidden menu. If you don´t select one you can press the menu button again to hide the menu.
Thats how it should work.
Because a user can add a unlimited number of menu items there is no way to present all menu links on the viewable part of your mobile only at a certain amount of items. But scrolling up and down the menu is normally a common and elegant solution for it...
