django-mptt-admin is a reusable Django application that provides an interactive tree view interface in the Django admin for models using django-mptt (Modified Preorder Tree Traversal). It enables drag-and-drop reordering, inline editing, adding child nodes, filtering within subtrees, and a grid view alternative. The backend is implemented as a Django admin mixin (`DjangoMpttAdminMixin`) that handles tree JSON serialization, move operations, and changelist customization. The frontend is a TypeScript integration layer that initializes a tree widget (using the tree-element library) and manages CSRF-protected AJAX move requests, loading spinners, and error handling. The repository includes a full example project with tests (unit, view, and Playwright), CI/CD pipelines, and internationalization for multiple languages. It is actively maintained, with recent major version 3.0.0 that replaced the previous jqTree library with a modern jQuery-free tree widget.
