Thanks for your help, but found out it was another issue. I positioned the underline right above the border bottom line of the main menu. This worked perfekt except with the mega menu. The reason: there is an “overflow:hidden” style added to each mega menu items. Changed it to visible and now everything works like a charm.

Funny how some problems really seem to be a bigger issue… they cost you nerves and time … and finally you found out that you were looking at the very wrong place and the solution is so simple you could kick yourself in the ass :-D.

forget my last comment. .current_page_parent a { } did the trick :)

WOW – thanks for the fast reply! Works perfectly.

As for my 2nd question: any help would be appreciated :).
