I'm using the superfish menu at http://themeforward.com/demo2/

A good example of what I'd like to achieve can be found at http://designmoo.com/ Notice how the parent menu item "Resources" retains its hover styling when mousing over the submenu... I would like to achieve this with Superfish.

Right now the parent menu item doesn't retain it's active styling when I go through the submenu, here is my css:

  /*** ESSENTIAL STYLES ***/
.sf-menu, .sf-menu * {
    margin:         0;
    padding:        0;
    list-style:     none;
}
.sf-menu {
}
.sf-menu ul {
    position:       absolute;
    top:            -999em;
    width:          10em; /* left offset of submenus need to match (see below) */
}
.sf-menu ul li {
    width:          100%
}
.sf-menu li:hover {
    visibility:     inherit; /* fixes IE7 'sticky bug' */
}
.sf-menu li {
    float:          left;
    position:       relative;
}
.sf-menu a {
    display:        block;
    position:       relative;
}
.sf-menu li:hover ul,
.sf-menu li.sfHover ul {
    left:           0;
    top:            2.5em; /* match top ul list item height */
    z-index:        99;
}
ul.sf-menu li:hover li ul,
ul.sf-menu li.sfHover li ul {
    top:            -999em;
}
ul.sf-menu li li:hover ul,
ul.sf-menu li li.sfHover ul {
    left:           10em; /* match ul width */
    top:            -1px;
}
ul.sf-menu li li:hover li ul,
ul.sf-menu li li.sfHover li ul {
    top:            -999em;
}
ul.sf-menu li li li:hover ul,
ul.sf-menu li li li.sfHover ul {
    left:           10em; /* match ul width */
    top:            0;
}
