Dragable Javascript Treeview
<p>I need to develop a dragable and editable treeview. But I dont want to reinvent the wheel. Do you know a good paid or free javascripts to use?</p>

<p>I'm using jQuery so it could be a jquery addin to. I'll use treeview to display and edit sitemap structure. </p>

<p>And lastly, it is good if the componen supports json.</p>

<p>Thanks for your answer...</p>
