Django MPTT

django-mptt is a reusable Django application that simplifies the implementation of Modified Preorder Tree Traversal (MPTT) for hierarchical data in Django models. It provides tools for managing and working with trees of model instances, including automatic updates for tree structures, custom managers, and admin classes. The current version is 0.18.0, and while it continues to receive compatibility updates for newer Django and Python versions, the project maintainers note that the project is "currently unmaintained" in terms of active feature development, suggesting users consider alternatives for new projects.
