How can I make a menu option expand in android?
<p>I wrote this code in <code>mainactivty.java</code> </p>

<pre><code>@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    menu.add("About");
    return true;
}
</code></pre>

<p>It creates a menu, but I want it to open a new window when I click on the menu.</p>
