disable option in dropdown menu?

[carrajo]

Hi,

How can I disable an option in a drop-down menu? Specifically, I want
to disable the option "Bouncy Castles". I want to display it, I just
want the user to be able to select it. As well, how can I remove the
indentation?

Here's the drop-down menu:

<select name="stuff">
<optgroup label="A">
<option>Apple</option>
<option>Apricosts</option>
</optgroup>
<optgroup label="B">
<option>Ballon</option>
<option>Bouncy Castles</option>
<option>Beanies</option>
</optgroup>
</select>
