title: How to prevent menu from showing on mouse hover in this menu , and enable it to show only on mouse click?
body: <p>I downloaded the sm-blue menu from a site ( which I forgot the address , sorry ). By default it shows the submenu on mouse hover and mouse click. I want it to show the submenu only on mouse click. Here are codes :</p>
  
  <p>example of an application menu :</p>
  
  <pre><code>&lt;ul class="sm sm-blue pull-left" style="padding-bottom:0px;"&gt;
      &lt;li&gt;
          &lt;a href="javascript.void(0);"&gt;Menu title&lt;/a&gt;
          &lt;li&gt;&lt;a href="some_url"&gt;Sub menu&lt;/a&gt;&lt;/li&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>The sm-blue css :</p>
  
  <pre><code>@import url("googlefont.css");
