Struct Category Groups v1.0 (5.7-5.8) for Unreal Engine

In panels like Details or the DataTable row editor, Unreal ignores Category = “…” grouping for UPROPERTY members inside a nested C++ struct — everything renders as one flat list instead of collapsible groups. The usual workaround is splitting fields into nested sub-structs, but that only groups one layer deep and isn’t always desirable.
