Hello,
1) It’s possible by some additional customization. Add the icons in menu settings for the every secondary menu item http://prntscr.com/l7vgz6 and add the following code in child theme style.css
.secondary-menu-wrapper .menu>li>a i {
padding-right: 10px;
margin: 0 10px;
border-right: 1px solid #cdcbcb;
line-height: inherit;
}
.secondary-menu-wrapper .menu,.secondary-menu-wrapper .menu>li {
padding: 0;
}
.secondary-menu-wrapper .menu>li>a {
line-height: 2;
padding-bottom: 0;
padding-top: 0;
border-bottom: 1px solid #cdcbcb;
padding-right: 30px;
}
.secondary-menu-wrapper .menu li.menu-item-has-children>a:before {
padding: 0 10px;
line-height: 31.92px;
background-color: #f2f2f2;
}
.header-advanced .secondary-title, .header-advanced .secondary-menu-wrapper .menu {
width: 310px;
}
2) To make the main header as the fixed header disable the fixed header in theme options and try to add the following code in child theme style.css
.header-wrapper{
position:fixed;
top:0;
z-index: 10000;
}
.admin-bar .header-wrapper {
top: 32px;
}
.content-page, .page-content {
margin-top: 195px;
}
