Drag and drop tree

[Malthe Borch]

Hello list, –––

I did some research on drag and drop nested sortables, which we
considered for letting users move content around.

There are three reasonable offerings, namely:

- jsTree (http://www.jstree.com/jsTree/examples)

- NestedSortablesWidget
(http://www.bernardopadua.com/nestedSortables/test/widget)

- Nested list (http://www.swartzfager.org/blog/dspNestedList.cfm)

I believe the first one is the most complete and supported; I tried to
integrate but had some error which I'll investigate further.

Then I came upon this development document:

- http://jqueryui.pbwiki.com/Tree

Basically it seems that the UI team is in the process of developing a
standard widget for this sort of thing. Perhaps then, we should wait a
few months until it's ready and meanwhile implement a simpler
interface.

Challenges:

- We probably don't want to load the entire tree at once, although
this is probably not a real concern at first.

- Not all content can be dragged to all places; only if the content
type is addable at the drop point should we allow it. I'm not sure how
we'd configure the plugins to take this into account.

i think for the backend implementation it doesnt make a big difference which interface we use.

i would for now use NestedSortablesWidget since it seems like it provides all features out of the box.

when jquery ui releases the plugin we can implement it. dont think its a good idea to wait for them.

if thats ok i will provide a markup with NestedSortablesWidget.

the NestedSortablesWidget has that support
