Easy: Addclass removeClass hasClass issue?
<p>I have some buttons in a container div that need to toggle active but only 1 active button at a time. </p>

<p>EDIT:</p>

<p>html is: 
div container of .filter(btn, btn, btn, etc)
there are 3 containers of buttons. 
The third container has a button with an id of: #filter1-none</p>

<p>The code below works to have only 1 button active per group. </p>

<p>Additionally, how would I remove active only from the button with an ID of #filter1-none ONLY if any of the other buttons are active?</p>

<pre><code>$('.filter .btn').click(function () {
    $(this).addClass('active').siblings('.active').removeClass('active');
});
</code></pre>
