Toggling an "active" class between cousins
<p>So I currently have three unordered lists in my header. This is a single-page site that uses anchors to navigate. I need to have an "active" class to toggle between any anchor that is clicked between these three unordered lists. I still relatively new with jQuery and programming in general, but the basic structure of the page is outlined below.</p>

<pre><code>&lt;div id="header"&gt;

&lt;div id="brands-nav"&gt;

    &lt;h3&gt;Brands:&lt;/h3&gt;

    &lt;ul class="navitems"&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchore&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;

&lt;/div&gt;

    &lt;div id="mediums-nav"&gt;

    &lt;h3&gt;Mediums:&lt;/h3&gt;

    &lt;ul class="navitems"&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;

&lt;/div&gt;

&lt;/div&gt;

    &lt;div id="about-nav"&gt;

    &lt;h3&gt;About:&lt;/h3&gt;

    &lt;ul class="navitems"&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="#"&gt;Anchor&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;

&lt;/div&gt;
</code></pre>

<p></p>

<p>So, I am trying to figure out how to add an "active" class to any of those that are clicked as well as removing the active class from any cousins.</p>

<p>I understand the basic way to do this if all the elements are contained by the same parent with something like this...</p>

<pre><code>$(document).ready(function(){

$("#mediums-nav a").click(function(){
  $(this).toggleClass("active");
  $(this).siblings("a").removeClass("active");
});
</code></pre>

<p>});</p>

<p>So how would I go about extending that to all of it's cousins?</p>
