margin:0;
padding:0;
list-style:none;
float:left;
position:relative;
z-index:10000;
}

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

/*Top level menu link items style*/
#menu ul.ddsmoothmenu li li {
width:auto;
font:11px Arial, Helvetica, sans-serif !important;
text-transform:capitalize;
margin:0;
padding:0;
}

#menu ul.ddsmoothmenu li li a{
width: 130px; /*width of sub menus*/
height:auto;
float:none;
display: block;
text-align:left;
color: #fff;
text-shadow:none;
margin:0;
padding:6px 18px;
text-decoration: none;
background:none;
position:relative;
border-bottom:1px solid #EEEEEE;
}

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

#menu ul.ddsmoothmenu li li a:link, #menu ul.ddsmoothmenu li li a:visited{
color: #888888;
background:url(../images/submenu_px.gif) top repeat-x #fff;
}

#menu ul.ddsmoothmenu li li a.selected,
#menu ul.ddsmoothmenu li li a:hover { /*CSS class that's dynamically added to the currently active menu items' LI A element*/
color: #fff;
background:#4E4E4F;
}
    
/*1st sub level menu*/
#menu ul.ddsmoothmenu li ul{

padding:0;
position: absolute;

}
