You can try this though:

****************************************************
<html>
<head>
<title></title>

<style TYPE = "text/css">
.category{background-color:blue;color:white;}
</style>

</head>
<body>
<form NAME = "frmSelect">

<select name="Test" size="1">
<option value="This one is BOLD" CLASS = "category">This one is BOLD</option>
<option value="This one is NOT">This one is NOT</option>
<option value="This one is NOT">This one is NOT</option>
<option value="This one is BOLD" CLASS = "category">This one is BOLD</option>
<option value="This one is BOLD" CLASS = "category">This one is BOLD</option>
</select>

</form>
</body>
</html>

****************************************************

You can change the background color and font color in the select boxes.
