how to disable a html:option tag?

[Dirk Manske (Service Respond)]

Hi,
 
I have in a form a html:select tag and inside some html:option tags. I want
to disable some options and declared it like this
 
<html:select ...>
 
<html:option value="1" disabled="true">optionText</html:option>
 
</html:select>
 
But this seems not to work because this option is still selectable. How to
solve it?
 
thx,
Dirk
