title: Add a <div> after <li> in wordpress
body: <p>I use this script to show the wordpress menu</p>
  <pre><code>&lt;?php  
     $argsM = array(
        'theme_location'  =&gt; 'menu-principal',
        'items_wrap'      =&gt; '&lt;ul class=&quot;sf-menu nav navbar-nav %2$s&quot;&gt;%3$s&lt;/ul&gt;',
     );
     wp_nav_menu( $argsM );
  ?&gt;
  </code></pre>
  <p>And it gives me a regular menu as</p>
  <pre><code>ul
    li - home
    li - shop
    li - contact us
  ul
  </code></pre>
  <p>I try to find a way where I can put a div after each li for something similar to this</p>
  <pre><code>ul
    li - home
     div
    li - shop
     div
    li - contact us
     div
  ul
  </code></pre>
  <p>I want to go this way if it's possible and not with a jQuery solution .append() or something else like that.</p>
