[jQuery] [Treeview] Dynamically adding nodes to the async treeview

[SirHoundalot]

Hi all

I'm using the async version of the treeview plugin by Jörn Zaefferer.
I'd really like the ability to dynamically add nodes to the treeview,
but am experiencing some difficulties in doing so.

Currently I've managed to get top-level leaf nodes added using the
following code:

function addNode(cssClass,newName){
                var node = $("<li><span 
class='"+cssClass+"'>"+newName+"</span><ul></
ul></li>").appendTo("#products");
                $("#products").treeview({add: node});}

where #products is the id of the ul that contains the tree.

I can't work out how to add nodes elsewhere in the hierarchy though -
is there a way to specify which parent to add the new nodes to?

Thanks!
