jQuery selector for select box options?
<p>I have a few multiple select boxes. </p>

<p>In each box, there are a few options you can click on, as well as a category "ALL". </p>

<p>I want to make it that when you select ALL, the rest of the options in that box become disabled. I need to have a way to select the rest of the options in the box and I'm not sure exactly how.</p>
