Responsive Menu trouble

Hi everyone and hotThemes Team,

I got some trouble with the OnePage responsive menu.
Please take a look to the attached file.
The site is life under www.silvergel-matratzen.de .

The problem occurs when scale the layout very smal or look at the site
with a smartphone. Logo is up and the menu is one row under.
Also this "Impressum" menu item is outside the drop-down box.

Can someone help me in that issue please?
I guess it has something to do with "mp_log", "mp_topmenu", "cell_pad" and the "container" row.

Hope for your reply. Thanks.

Best regards Bjoern

That is intended , if you want to keep it in same row in index.php of tempalte:

in
[class*="span"] {
width: 100%;
}

remove width: 100%;

it doesn't work for me,
Many thanks for your help!

Open layout.css

select.tinynav {
text-indent: -9999px;
margin-top: 10px;
}

change to:

select.tinynav {
text-indent: -9999px;
margin-top: 30px;
}
