I want the drop down menu as it is now, however orthopedics/sports is always underlined, how can I remove that 

below is the code i am using currently

.header-nav .header-nav-item--folder .header-nav-folder-content{
 font-weight: bold;
}

a.header-nav-folder-title:hover + div, .header-nav-folder-content {
    text-align: left !important;
    position: absolute;
    left: 100% !important;
    right: 0% !important;
  -webkit-transform: translatex(-50%);
    -o-transform: translatex(-50%);
    transform: translatex(-50%);
  background: transparent !important;
}

thanks
