I have download that slashdotmenu from this site and work very well, But am try to create functions for a: active for sub links, how can I do that? I have add same tags a:hover but like this.

.sdmenu .submenu a:hover {
background : #066 url(linkarrow.gif) no-repeat right center;
color: #fff;
}

.sdmenu .submenu a:active {
background : #066 url(linkarrow.gif) no-repeat right center;
color: #fff;
}

I cant get that a:active work and it just turn to default. Anyone knows how to fix it? Maybe it need cookies setting and not css?
