I have a query about implementing SiteTree-like hierarchy in ModelAdmin.
First of all, is it possible? I need to manage my objects, with categories (and an indefinite number of sub categories) in ModelAdmin. Ideally, I'd like basically another SiteTree in another tab, to avoid the clutter of the other pages.
It is possible, I used to have a systen that used the sitetreeasUL functions and created one from data objects. But I replaced it with modeladmin (as it was hacky and tons of code).
SS3 will be using jstree and it looks very simple to create a tree from a dataobject set...
This could show the dataobjects found by the search as the root nodes,
clicking on the icon brings up the normal edit form and clicking on
the pluss opens up the "child" or relating objects.
It would need...
*icon (as you say)
*a way to indicate relationships not to follow (in other words "sink"
