A module for ProcessWire CMS/CMF. For any page, allows the restricting of templates that may be used for child pages.
Install the TemplatesChildPages module. The module adds an AsmSelect inputfield "Template restrictions for children" on the Children tab of Page Edit. Use the inputfield to select from existing templates and any child pages added subsequently will be limited to those selected templates.
Note that any template restrictions added via this module are in addition to any "Family" restrictions set for the child and parent templates. In other words, if template Family restrictions prevent a template being selected for a given page you can't override this simply by including the template in the parent's "Template restrictions for children" field.
The module allows you to add child page template restrictions without having to create new or duplicate templates for the parent page. This forum post explains the situation well.
Similarly, it makes it possible to use the "Add New" page feature without an unnecessary proliferation of templates. If you specify a single template as restriction for child pages you can add a Page Add Bookmark for that parent page that allows site editors to easily add a new page using the right template for the location.
