Add limits to page blueprints

[tognee]

Blueprints can be used to add different types of entries in the pages collection. These blueprints let you define a template and fields that differ from the default page.

I'm proposing to add some fields or yaml properties to limit page creation and position.

max_num and max_num_per_parent

This limit should let you set a maximum number of pages with that blueprint that can be added in the pages tree or under a specific parent.
For example:

• A Contact us page could have a max_num of 1, since it should be added only once.
• A Service addendum page could have a max_num_per_parent of 1, since there could be only one addendum per service.

After that it should no longer be visible in the create new entry and add child entry menus.

parent_types and child_types

This limit should let you set child blueprint types and parent blueprint types.
For example:

• A Contact us page that cannot have any other children: child_types: []
• A Service addendum page that should only be added under a Service page and have no children: parent_types: ['service'] child_types: []
• A Folder page that cannot contain other Folder pages: parent_types: ['!folder'] child_types: ['!folder']

This should remove the options in the "create new entry" if the blueprint type cannot be added under the root entry, and from the "add child entry" menu if the blueprint doesn't support that kind of parent or if the parent doesn't support that kind of child.
This should also limit drag and drop of the entries with these blueprint in the tree view.

Hey 👋

Feature requests usually live in the statamic/ideas repository. Would you be able to open an issue there instead?

Thanks, didn't see that 👍
