CSS:
.menu-large {
position: static !important;
}
.megamenu {
padding: 20px 20px;
width: 100%;
}
.megamenu > div > li > ul {
padding: 0;
margin: 0;
}
.megamenu > div > li > ul > li {
list-style: none;
}
.megamenu > div > li > ul > li > a {
display: block;
padding: 3px 20px;
clear: both;
font-weight: normal;
line-height: 1.428571429;
color: #333333;
white-space: normal;
}
.megamenu > div > li > ul > li > a:hover,
.megamenu > div > li > ul > li > a:focus {
text-decoration: none;
color: #262626;
background-color: #f5f5f5;
}
.megamenu.disabled > a,
.megamenu.disabled > a:hover,
.megamenu.disabled > a:focus {
color: #999999;
}
.megamenu.disabled > a:hover,
.megamenu.disabled > a:focus {
text-decoration: none;
background-color: transparent;
background-image: none;
filter: progid: DXImageTransform.Microsoft.gradient(enabled=false);
cursor: not-allowed;
}
.megamenu .dropdown-header {
color: #428bca;
font-size: 18px;
}
.megamenu .container{
background-color:#f4f4f4;
}
@media (max-width: 768px) {
.megamenu {
margin-left: 0;
margin-right: 0;
}
.megamenu > li {
margin-bottom: 30px;
}
.megamenu > li:last-child {
margin-bottom: 0;
}
.megamenu.dropdown-header {
