Hello again.
Your bugfix works fine in safari.
But I just saw that it produces a new bug in chrome browsers. I’ve testet it … if I delete it again, everything works fine in chrome.
In the horizontal version you can see the bug here:
http://www.siquando-templates.de/
If you move the mouse over ‘Siquando Templates kaufen’, you can see, that the second level of the menu disappears behind the search-button.
In the vertical version you can see the bug here:
http://www.testsite.siegmann.ws/kick_v/tabelle/index.php
‘Tabelle’ has a class .current. If you move the mouse over ‘Testseite’, you can see that the second level disappears behind the red of the .current class.
