How do i use <option disabled> with IE6

HI,

How do i get the following to work in IE6

<select name="my menu">
<opttion value="dont" disabled>dont show me</option>
</select>

The above peice of code wil work nicely in most other browsers but IE6 does
not grey out teh option it jsut lets the user select it and submit the
value. Yet Opera, Netscape 7 etc do not do this.

Does anyone know how I would make thsi work in IE6??
