###### Models ###### .. class:: cms.models.Page A ``Page`` is the basic unit of site structure in django CMS. The CMS uses a hierarchical page model: each page stands in relation to other pages as parent, child or sibling. This hierarchy is managed by the `django-treebeard `_ library. A ``Page`` also has language-specific properties - for example, it will have a title and a slug for each language it exists in. These properties are managed by the :class:`cms.models.Title` model.
