You can use ergonomic property list administration interface to easily administrate those dynamic data structures.

You must set this Configuration option:

key=RootIds,componentType=DataStructurePropertiesList

like ,1,2,3,

Those lists will be displayed at the top.

Then all sublists will be rendered as children.

Orphan childs will be displayed in separate menu after all those lists

You can see it in view DataStructurePropertiesList/Administration/Hierarchy.
