title: How to add default Widgets to a custom dynamic sidebar
body: <p>I have added my custom dynamic sidebar using this code in WordPress</p>
  
  <pre><code>register_sidebar
  (array(
  'name' =&gt; __( 'My widget' ),
  'id' =&gt; 'right-sidebar',
  'description' =&gt; __( 'Widgets in this area will be shown on the right-hand side.' ),
  'before_title' =&gt; '&lt;h1&gt;',
  'after_title' =&gt; '&lt;/h1&gt;'
  ));
  </code></pre>
  
  <p>Now I can see this dynamic sidebar in the WordPress admin, via Dashboard -> Appearance -> Widgets.</p>
  
  <p>When I activate the Theme, by default this dynamic sidebar displays no content; to display Widgets (e.g. Recent Posts, Pages, Category) I have to drag them into the My Widget dynamic sidebar.</p>
  
  <p>But I want the My Widget dynamic sidebar to display three Widgets (Recent Posts, Pages, Category) by default, similar to the dynamic sidebars in Twenty Ten or Twenty Eleven.</p>
