About Controlling the Page Hierarchy in Wagtail

In Wagtail, you can programmatically set parameters like max_count, parent_page_types, and subpage_types to control the hierarchy of page navigation that content editors will create, e.g.:

from wagtail.models import Page

class HomePage(Page):
    # only one home page allowed per website
    max_count = 1
    # must be at the root
    parent_page_types = ["wagtailcore.Page"]
    # subpages can be of these types
    subpage_types = [
        "standard_pages.StandardPage",
        "form_pages.FormPage",
    ]
