title: main menu on wordpress theme is not carried over to new copy-pasted theme
body: <p>Sorry, new to Wordpress here.</p>
  
  <p>I copy-pasted an existing theme. Most of it looks fine. However, it seems the main menu style and menu items were not carried over to the new theme. The new theme is unstyled because it has no id <code>menu-top</code>, which the original one has. Also, the new theme has way too many menu items, while the original one only has 4.</p>
  
  <p>What do I change so that my new theme's main menu gets that id, and will contain the same menu items?</p>
  
  <p>I've check the Admin > Appearance > Menu and it correctly has 4 items, but it's not reflected in my new theme.</p>
  
  <p>Also, in header.php, I tried adding <code>'menu_id' =&gt; 'menu-top'</code> to:</p>
  
  <p><code>wp_nav_menu( array( 'container'=&gt;'none',  'theme_location' =&gt; 'primary' ) );</code></p>
  
  <p>but that didn't change anything.</p>
  
  <p>Help please?</p>
