SUInsertion + SUSortable - Evalscripts needed?

I have a nested, tree-like structure of items.

I allow SU-insertion of nodes into that tree.

The children of any node (including subtrees) are sortable, including newly
inserted nodes.

Any sketch of what I need to do this? I have tried a couple of things,
including trying to sprinkle an #evalScripts: true someplace, without much
luck. My code is somewhat convoluted, includes a fair bit of domain
specifics, and is ugly, so I have not posted it ...

Thanks - Sophie

Presumably this won't work as script.aculo.us has some well known
problems with drag and drop of nested elements. As you can read in the
documentation [1] you have to pay attention to the order you register
the droppable. Sortables have a tree option [2] that probably goes
into the direction you want, but it is slow and rather buggy. For me
none of these techniques worked in all browser. I had to write my own
JavaScript code to get drag and drop for nested elements.

> #evalScripts: true

That's default for quite some time now.

Cheers,
Lukas

Ah, that sounds like the source of my problemn, and seems difficult to work
around with dynamically inserted nodes.

Any chance this is non-commercial / shareable?

Thanks - Sophie

No probably not. It only works for a very specific use-case anyway.

Try to make your objects non-nested. This usually works. For example
for a tree, you just make sure that you don't drag the node with the
children, but just the node itself. In the picture below this means
you just drag around the <..>-part.

I ended up using a SorterView (purely dedicated to sorting a flat list,
nothing else) that I used through #lightbox: Good enough for now. I will try
your suggestion later, the Ajax advantage is too much to ignore.
