title: Category exclusion in Wordpress
body: <p>I'm working on this Wordpress website - <a href="http://adsclip.com/" rel="nofollow">http://adsclip.com/</a></p>
  
  <p>I've built a country selector using this code (in it's simplest form)</p>
  
  <pre><code>&lt;select name="countries" id="countries" style="width:180px;" onchange="return change_action(this.value);"&gt;
  &lt;option value='us' id="us"&gt;United States&lt;/option&gt;
  &lt;option value='gb' id="gb"&gt;United Kingdom&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>The posts throughout the Wordpress are grouped into country categories, my aim to exclude categories throughout the website when a specific country is selected.</p>
  
  <p>If possible I'd like to just exclude them from the homepage.</p>
  
  <p>Is there a plugin, or some code that can help me achieve this?</p>
