Entitree provides a tree structure to content entities in a Drupal site. Along with the structure itself, Entitree provides tools to enable support for entity types as well as an API for accessing the tree structure. Once an entity type is made available, all entities of that type can be added to the tree.
Included Submodules
Entitree Node
Support for the Node (content) entity type is provided in a submodule. This module must be enabled for Node support to be provided.
