Thanks for reply. That I should do the normal menu? can not be cut-off to the right?
I also try to put search bar under the icons but the icon is still shifted to the left and it looked weird.
As for the menu, there not should be a fixed width? If so, where can I change it? And how I can do level / three rows menu?
You have ran out of room; it is as simple as that. I also noticed the menu is cut-off to the right. The normal menu uses a table to construct the menu.
Let's start with the icons. To give them more room, remove or relocate the search box. You could relocate the search box to under the icons; this will increase the height of the header but will give room for the icons to move over.
As for the menu, look at the CSS code controlling the menu to see if it is fixed width; you might could rewrite it so the menu will fold under itself as the screen gets narrower; it won't look pretty of course. Or maybe you could have three levels/three rows of menu items so that it will still look pretty on the narrower screen.
