Hi
@Deleted User, there's nothing in the Contentment's Data List editor that supports hierarchical data. I had considered the potential for developing one, but I never had an actual need for it on a project (so got put on the backburner ideas pot). What I did consider was that an MNTP-style editor would be better suited for hierarchical structures... but designing it to use Umbraco Trees, (i.e. the
ITree
and
ITreeService
interfaces), then a custom data-source could implement a custom
ITree
and the DataType configuration would select that tree-source. (Basically what MNTP could have been, not fixed to Content/Media/Member trees)
