Tree Menu Method
<p>I'm creating a menu with the following structure in the database:</p>

<pre><code>MenuItems
  id
  menu_text
  id_parent
</code></pre>

<p>Where <code>id_parent</code> is null, this is a menu root, and if <code>id_parent</code> is not null, this is a part of submenu.  I need to create a method to return an tree of this contenxt, and then return a string with <code>&lt;UL&gt; &lt;LI&gt;</code> sctructure to render in my webpage.</p>

<p>I cannot figure out the query to select all of the menus and their direct sub menus at once.</p>
