I want to limit 3+ select boxes to only pick one <option> once - what am I doing wrong?
<p>I set up my jQuery <a href="http://jsbin.com/afudo3/8/edit" rel="nofollow">like so</a>.</p>

<p>It successfully lets me pick an option only once throughout the 3 dropdowns.</p>

<p>However, if I remove a dropdown (use the convenient button), an option is forever disabled (greyed out).</p>

<p>You'll see what I mean. First, ensure that it works and you can not select the same option more than once.</p>

<p>Now, remove and notice that one has been disabled, and it can never be selected again.</p>

<p>I don't know why it is forever greying out my option? It seems to keep picking it up when making the <code>selectedIndexes</code> array.</p>

<p>Does anyone know how to get around this problem?</p>
