title: "Object expected" when calling "dropdown()" in IE7
body: <p>The following code works in Firefox but in Internet Explorer it returns error "Object expected".</p>
  
  <pre><code>  &lt;html&gt;
    &lt;head&gt;
    &lt;script type="text/javascript"&gt;
     dropdown("navigation", "auto")
    &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
    &lt;div id="navigation"&gt;
    &lt;ul&gt;
       &lt;li&gt;&lt;a href="hhdh/"&gt;&lt;span&gt;Home&lt;/span&gt; &lt;/a&gt;&lt;/li&gt;
       &lt;li&gt;&lt;a href="hhdh/"&gt;&lt;span&gt;All&lt;/span&gt; &lt;/a&gt;&lt;/li&gt;
        &lt;ul&gt; 
             &lt;li&gt;&lt;a href="sss/"&gt;&lt;span&gt;submenu&lt;/span&gt; &lt;/a&gt;&lt;/li&gt;
             &lt;li&gt;&lt;a href="sss/"&gt;&lt;span&gt;submenu&lt;/span&gt; &lt;/a&gt;&lt;/li&gt;
       &lt;/ul&gt;
    &lt;/ul&gt;
    &lt;/body&gt;
    &lt;/html&gt;
  </code></pre>
  
  <p>I cannot find documentation for the function dropdown anywhere.</p>
