It depends what menu u´re using…
So if you´re using the default: splitmenu, you have to change the background definition in following part at your ja-splitmenu.css file. ($ja_menutype = 1)
#ja-splitmenu li.active a,
#ja-splitmenu li.active a:hover,
#ja-splitmenu li.active a:active,
#ja-splitmenu li.active a:focus {
border-top: 5px solid #181818;
padding: 7px 15px;
background: #181818;
}
ja-sosdmenu.css ($ja_menutype = 2)
#ja-cssmenu li a.active {
border-top: 5px solid #181818;
background: #181818;
color: #FFFFFF;
}
ja-transmenuh.css ($ja_menutype = 3)
a.mainlevel-active-trans {
border-top: 5px solid #181818!important;
color: #FFFFFF;
background: #181818;
}
