Do you have this live somewhere? If not, also post the html, and place both in code=css and code=html tags.
This belongs in html&css, by the way, as your own title suggests.

try to use this a simple hover css properties..no drop down but it works, or just copy the basic format for the buttons. I think your css codes has no problem ..is all your "li" has already an ahref link, and open/close with the "ul".

li {
float:left;
width:150px;

}

ul {
list-style-type: none;
height: 100px;
width: 750px;
margin: auto;

}

ul a {
background-image:url(image/button2.png);
background-repeat: no-repeat;
background-position: right;
padding-right: 50px;
padding-left: 50px;
display: block;
line-height: 80px;
text-decoration: none;
font-family:Arial, Helvetica, sans-serif;
font-size: 18px;
color: #371C1C;
}

ul a:hover {
color:#FFFFFF;
background-image:url(image/button.png);
}
