}
#nav ul li ul li:hover{ background: #f1f1f1; }
#nav ul li ul li a:hover{ color: rgba(253,183,46,1); }


nav li:hover > nav li ul li{
    background-color:red;
    overflow:visible;
}
nav li ul li{
    display:none;
}

Answer 1

try this:

    nav ul li ul li{
    display:none;
}

    nav ul li:hover > ul li{
        display:block;
    }
