<h4>Advanced Usage</h4>
If you want to assign custom sidebars to archive pages or replace multiple sidebars per page, this plugin likely won’t be the best solution. However it’s flexible enough to handle a wide range of page-based use cases. It can even be configured to work with Custom Post Types by adding a couple lines of code:
<pre><code>function myprefix_init() {
 add_post_type_support( '{{post_type}}', 'multiple-sidebar-generator' );
}
add_action( 'init', 'myprefix_init' );
</code></pre>
