The vmart module just outputs links instead of an unordered list like they should.
You’ll need to edit /templates/jp_techpraise_1.5/css/theme1.css (or the theme you’re using)
and add this
/*
* Virtuemart Menu
*/
.moduletable_content a{
display:block;
padding:2px 2px;
border-bottom:1px dotted #C8CACA;
//border-top:1px dotted #FDFDFD;
//color:#666;
text-decoration:none;
}.moduletable_content a:hover {
background-color:#F0F0F0;
}a#active_menu {
color:#cc0000;
background-color:#b02500;
}
