Document Page Mgmtsystem

This module extends the Documents/Wiki pages feature (document.page) with an extra classification field called "Management System Page Type".

What users see: - On the document page/category form, a new field appears right after the Company field. - In the document page search filters, the same field is available so pages can be filtered by type.

Automatic behaviour: - The field is computed from the parent page's value: a child page automatically takes the management-system type of its parent. - For a page of type "category", if no value is inherited from a parent, the category keeps its own value. - The value is stored in the database and the computation follows the parent chain (recursive), so changing a parent can update its children. - The field is editable (not read-only), so users can set it manually where needed.

Important limitation: the list of selectable values is empty in this module. It is designed as a base field to be filled in later by other modules, so in practice users will not see predefined options until another module provides them.

Areas touched: the document.page model and its category form and wiki filter views from the document_page module.
