I looked for the post but not sure what style only menu you are talking about. I might be using it already. I have the stylesheet_categories_menu.css. It looks like this


Code:
body {  
         behavior: url(includes/csshover.htc);
} /* WinIE behavior call */

/* EXTRA LINKS Background Color  and width */








div#nav-cat {
     margin-top: 0em;
     background-color: #eeff99;
	 color: #000000;
     width: 100%;
	 height:95%;
	 line-height:20px;
     margin-left: auto;
     margin-right: auto;
     font-weight: bold;
     font-size: 1.3em;
}
	

div#nav-cat ul {
         margin: 0; 
         padding: 0; 
         width: 155px; 
         background-color: transparent;
         z-index: 1000;
  /*border: 1px solid #ff0000;*/
}

/*
div#nav-cat ul.level2 {background-color: #c65928; width: 180px;}
div#nav-cat ul.level3 {background-color: #c65928;}
div#nav-cat ul.level4 {background-color: #c65928;}
div#nav-cat ul.level5 {background-color: #c65928;}
div#nav-cat ul.level6 {background-color: #c65928;}
*/

div#nav-cat li {
    z-index: 20; 
        position: relative; 
        list-style: none; 
        margin: 0;
		height: 20px;
		width: 150px;
		/*add border below or above products on the menu*/
		
    margin-top: 0px; /* change it to whatever space you want to put space between buttons*/
    border-bottom: 0px solid #679966; /* <---this line may help or hinder IE menu shifting issues */
	border-top: 0px solid #679966; /* <---this line may help or hinder IE menu shifting issues */
}
div#nav-cat li li {
    margin: 0; /* this overrides the margin-top in the declaration above */
} 







/* submenu hover over background color */


/* Products menu background color */
div#nav-cat li.submenu {background-color: #eeff99;}


/* Products menu hover over background color */
div#nav-cat li.submenu:hover {background-color: #eeff99;}

/*padding around product text css menu*/

div#nav-cat li a {
        display: block; 
        padding: 0em 0em 0em;
    text-decoration: none; 
        width: 160px; 
        color: #132e12;
}

div#nav-cat ul a {
        width: auto;
}

div#nav-cat ul ul {
        position: absolute; top: 0; left: 100%;
    display: none; z-index: 1000;
	
}



div#nav-cat ul.level1 li.submenu:hover ul.level2, 
div#nav-cat ul.level2 li.submenu:hover ul.level3,
div#nav-cat ul.level3 li.submenu:hover ul.level4,
div#nav-cat ul.level4 li.submenu:hover ul.level5,
div#nav-cat ul.level5 li.submenu:hover ul.level6 {
        display:block; 
		
		/* submenu background color */
        background-color: #eeff99;

I have messed with lots of these color numbers and couldn't get it to change the subcategory hover over links or the Product hover over link.
