<h1>Example: Context Menu</h1>
<p class="description">
Implementation of a context menu. Right-click a node and see what happens.<br>
Also [space] key is supported to open the menu.<br>
<br>
This example also demonstrates, how to copy or move branches and how
to implement clipboard functionality.
<br>
A keyboard handler implements Cut, Copy, and Paste with <code>Ctrl-X</code>,
<code>Ctrl-C</code>, <code>Ctrl-V</code>.
</p>
<p class="description">
This sample uses the jQuery Context Menu Plugin by Cory S.N. LaViska.
Visit <a href="http://abeautifulsite.net/">A Beautiful Site</a> for usage and more information.
<br>
<b>NOTE:</b></br>
I had to <a href="http://code.google.com/p/dynatree/issues/detail?id=174">patch Cory's code</a> in order to make it work. Please understand, that I am not able to support this plugin. There are many other context menus
out there :-)
