Yii css dropdown menu?

Question

css

I can’t figure out where to set the z index of the container so that the menu is higher than the
css slider container

.jqueryslidemenu{
font: bold 12px Verdana;
background: #414141;
width: 100%;

}

.jqueryslidemenu ul{
margin: 0;
padding: 0;
list-style-type: none;
}

/*Top level list items*/
.jqueryslidemenu ul li{
position: relative;
display: inline;
float: left;
}

/*Top level menu link items style*/
.jqueryslidemenu ul li a{
display: block;
background: #414141; /*background of tabs (default state)*/
color: white;
padding: 8px 10px;
border-right: 1px solid #778;
color: #2d2b2b;
text-decoration: none;
}

* html .jqueryslidemenu ul li a{ /*IE6 hack to get sub menu links to behave correctly*/
display: inline-block;
}

.jqueryslidemenu ul li a:link, .jqueryslidemenu ul li a:visited{
color: white;
}

.jqueryslidemenu ul li a:hover{
background: black; /*tab link background during hover state*/
color: white;
}
  
/*1st sub level menu*/
.jqueryslidemenu ul li ul{
position: absolute;
left: 0;
display: block;
visibility: hidden;
}

/*Sub level menu list items (undo style from Top level List Items)*/
.jqueryslidemenu ul li ul li{
display: list-item;
float: none;
}

/*All subsequent sub menu levels vertical offset after 1st level sub menu */
.jqueryslidemenu ul li ul li ul{
top: 0;
}

/* Sub level menu links style */
.jqueryslidemenu ul li ul li a{
font: normal 13px Verdana;
width: 160px; /*width of sub menus*/
padding: 5px;
margin: 0;
border-top-width: 0;
border-bottom: 1px solid gray;
}

.jqueryslidemenuz ul li ul li a:hover{ /*sub menus hover style*/
background: #eff9ff;
color: black;
}

/* ######### CSS classes applied to down and right arrow images  ######### */

.downarrowclass{
position: absolute;
top: 12px;
right: 7px;
}

.rightarrowclass{
position: absolute;
top: 6px;
right: 5px;
}

css for the container (via firebug)

.clearfix::after, .container::after {
    clear: both;
    content: " ";
    display: block;
    height: 0;
    overflow: hidden;
    visibility: hidden;
}
.clearfix, .container {
    display: block;
}
.container {
    margin: 0 auto;
    width: 100%;
}
body, div, span, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, code, del, dfn, em, img, q, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, dialog, figure, footer, header, hgroup, nav, section {
    border: 0 none;
    font: inherit;
    padding: 0;
    vertical-align: baseline;
}
body {
    color: #555;
}
body:not([id]) {
    cursor: auto !important;
}
