really simple:
i used the suggestion from m.freak
You must style it with css line25.com/tutorials/how-to-create-a-pure-css-dropdown-menu
you just need to paste this in your
templates -> jf_calla-exteriors-> css -> template.css file:
#jf-mainnav ul {
list-style: none;
position: relative;
}
#jf-mainnav ul ul {
display: none;
float:left;
clear:both;
position:absolute;
padding-top: 15px;
}
#jf-mainnav ul ul li {
float: none;
position: relative;
clear:both;
}
#jf-mainnav ul li:hover > ul {
display: block;
}
best wishes
