Hi,
i have different news categories on my site with sub-categories.
The issue I have: The background of the sub-categories is blue:

any idea how to set this blue background for the submenu items to the page background color?

Cheers
Ralf

Browser inspector says this is coming from the boostrap framework:

 .nav-pills > li.active > a, 
 .nav-pills > li.active > a:hover, 
 .nav-pills > li.active > a:focus {
     color: #fff;
     background-color: #337ab7;
  } 

So you need to override that somehow.
