JQuery : ul on hover for dropdown

Trying to use jQuery's hover to visible/hide a ul item to give dropdown effect.

Here is the jQuery. Ignore the alert functions

$(document).ready(function () { 

    $('ul.drop li').hover(
        function () {
            alert("asa");
            //show its submenu
            var isVisible = $(this).next('ui').is(':visible');
            alert("dvData is " + isVisible);
            var isHidden = $(this).next('ui').is(':hidden');
            alert("dvData is " + isHidden);

            $(this).next('ul').css({visibility: "visible", display: ""});

        }, 
        function () {
            //hide its submenu
            $(this).next('ul').css({visibility: "hidden", display: ""});
        }
    );

});

Here is the jsp page 

<ul class="drop">
<li><a href="#">Main</a></li>
<li>Reporting
 <ul >
    <li><a href="#" target="_blank">Magellan Reports</a></li>
    <li><a href=""/>"  target="_blank">Script Reports</a></li>
 </ul>

<li><a href="<c:url value="#"/>"   target="_blank">CMS</a></li>
<li><a href="<c:url value="#"/>"  target="_blank">Operations</a></li>
</ul>

Here is the css

ul#nav {padding-left:16px;background-image:url(../images/buehne_5_intra.gif)}
clear {clear:both}
ul.drop a {color:#87A7CE;line-height:14px;display:block;text-decoration: none;
background-repeat:no-repeat;background-image:url(../images/diagonale_hauptnavigation.gif);background-position:right;
    height:10px;padding-right:22px; float:left;}
ul.drop, ul.drop li, ul.drop ul { list-style: none; margin: 0; padding: 0; background: #039;
color: #fff;}
ul.drop { position: relative; z-index: 597; float: left; }
ul.drop li { float: left; line-height: 1.0em; vertical-align: middle; zoom: 1; padding: 5px 10px; }
ul.drop li ul { visibility: hidden; position: absolute; top: 100%; left: 20px; z-index: 598; width: 150px; margin-left:50px;}
ul.drop ul a {color:#87A7CE;line-height:14px;display:block;text-decoration: none;height:10px;padding-left:10px; float:left;background-image:none;}
ul.drop ul li { float: none; }
ul.drop ul ul { top: -2px; left: 100%; }
.drop img{width:22px;height:24px;background-color:#039;margin-left:-20px;vertical-align:top}

I cud have done it with css alone, but some required,long, and corrupted css files are not allowing me to do so.. Please help with the jQuery.

next() looks for the next sibling, which matches nothing because you have no <ul> siblings for the triggering <li>. Instead, you'd want to look for the child, so try children() to find matching children. Modify your JS to the following:

$('ul.drop li').hover(
    function () {
        $(this).children('ul').css({visibility: "visible", display: ""});
    }, 
    function () {
        $(this).children('ul').css({visibility: "hidden", display: ""});
    }
);

You can view a demo here - http://jsfiddle.net/GoranMottram/Uxj2B/3/ - The CSS looks like it'll need a bit of work, but at least the JS is working.
