Showing and hiding <option> with jquery
<p>I have three selects (html drop down lists), all contain the exact same values (except the ids of selects are different).</p>

<p>Now I want to do this:</p>

<ul>
<li><p>When a user selects some option in the first select the same option is hidden in the other two. This rule applies to other two selects as well.</p></li>
<li><p>If the option in the second select is changed again then the previously selected option must reappear in the other selects.</p></li>
</ul>

<p>I hope I was clear. I know this should probably be solved with javascript but I don't have enough knowledge of it to write an elegant solution (mine would probably be very long). Can you help me with the this?</p>
