Adds a shortcode [pdfmenu] and a widget that defaults to displaying an unordered list of all pdf’s attached to the current page or post.
There are options for both altering the query to return a different set of attachments and for formatting the output.
This plugin should always default to:
<pre><code><ul class="cop_pdfmenu">
 <li class="attachment/pdf"><a href="(direct uri to attachment)" target="_blank" title="(attachment title)">(attachment title)</a>
</ul>
</code></pre>
The attachments will be ordered by date in the ascending order by default.
<h4>Shortcode Options include:</h4>
<ul>
<li>Change list types ol, li, div (nested divs).</li>
<li>
<ul>
<li>[pdfmenu list_type=”ul”]</li>
<li>[pdfmenu list_type=”ol”]</li>
<li>[pdfmenu list_type=”div”]</li>
</ul>
</li>
<li>Set a different class on the container.</li>
