The easiest, and highest rated way to Add Widgets to Posts and/or Pages. Create unlimited dynamic sidebars (widget areas) and insert these into a WordPress post or page.
Create as many widget areas (Turbo Sidebars) from the settings menu, and these can be used multiple times.
Each sidebar can be called independently by a shortcode, and you can call more than one per post/page.
Sidebars can be included in the post/page by using a shortcode like the following, where <code>x</code> is the name of the sidebar.
<pre><code>[widgets_on_pages id=x]
</code></pre>
