This plugin allows you to display random content anywhere on your site using a shortcode or widget. You can group your random content together, allowing you to display different content in multiple locations throughout your site.
The content is added via a custom post type, so you have full access to the tinyMCE editor. This allows you to easily add images, text, and links to your random content.
<h4>Using a widget</h4>
<ol>
<li>Navigate to Appearance->Widgets and add the Random Content widget to a sidebar.</li>
<li>Select a group from the dropdown. If you don’t create a group, the widget will use all entries.</li>
</ol>
<h4>Using a shortcode</h4>
Place the shortcode <code>[random_content]</code> anywhere on a post or page.
To choose entries from a specific group, add the <code>group_id</code> parameter. For example, <code>[random_content group_id="64"]</code>.
To specify the number of posts to show, add the <code>num_posts</code> parameter. For example, <code>[random_content group_id="13" num_posts="3"]</code>.

Random Content

Randomly display any content anywhere on your site.
