<p>Do you have a lot of categories and are sick of having a huge list in your sidebar?  Want to highlight only a few of them to make your site easier to navigate?</p>
<p>While redesigning WordPress sites for our clients we kept running into this problem over and over.  They had a huge list of legacy categories but only wanted to highlight a few of them.  We wrote this plugin to allow them to select which categories to show and which categories to initially hide.</p>
<p>All categories are still accessible by a “see all” link at the bottom of the list.</p>
<p>Add the widget to your sidebar to make it live.</p>


Category Expander

Allows WordPress Admins to show only a selected few categories on the sidebar and hide the rest from view until visitor clicks "See All".

<p>This plugin was created to show the categories for a single post in the sidebar.</p>
<p>The categories will be displayed in an unordered list.</p>
<p>You can choose the title for the widget in the sidebar if you wish.</p>
<p><strong>If you’re using the plugin, please drop the link to your blog <a href="https://wordpress.org/support/topic/plugin-posts-categories-in-sidebar-using-this-widget" rel="ugc">here</a>.</strong></p>
<p>Example:</p>
<pre><code><li id="cz_post_cat-3" class="widget-container widget_cz_post_cat">
    <h3 class="widget-title">Topics</h3>
    <div class="cz-post-cats">
        <ul class="cz-cat-ul">
            <li class="cz-cat-li"><a href="http://xxx.xxx.xxx/topic/facebook/">Facebook</a></li>
            <li class="cz-cat-li"><a href="http://xxx.xxx.xxx/topic/jobs/">Jobs</a></li>
        </ul>
    </div>
</li>
</code></pre>
<p>It uses the <code>is_single()</code> query in php so that it ONLY shows up on single posts. Not pages.</p>
<h3>Arbitrary section</h3>
<p>Anyone need any info here?</p>
