<h3>What does this do?</h3>
<p>Prints a bullet menu.</p>
<h3>How do I use it?</h3>
<p>Just insert the tag into your template/page like: <code>{bulletmenu}</code></p>
<h3>What parameters does it take?</h3>
<p>
<ul>
<li><em>(optional)</em> <tt>showadmin</tt> - 1/0, whether you want to show or not the admin link.</li>
<li><em>(optional)</em> <tt>collapse</tt> - 1/0, whether you want to collapse sub items that shouldn't be shown. Defaults to 0.</li>
<li><em>(optional)</em> <tt>start_page</tt> - the page id or alias (ie : 1.2 or 3.5.1 for example). This parameter sets the root node of the menu and only shows it and it's children. (a replacement for start_element)</li>
<li><em>(optional)</em> <tt>start_element</tt> - the hierarchy of your element (ie : 1.2 or 3.5.1 for example). This parameter sets the root node of the menu and only shows it and it's children.</li>
<li><em>(optional)</em> <tt>show_root_siblings</tt> - 1/0, if start_element (above) is given, then show direct siblings of the give start_element as well.</li>
<li><em>(optional)</em> <tt>number_of_levels</tt> - an integer, the number of levels you want to show in your menu.</li>
</ul>
