There are two different approaches to configuring a hierarchical relationship between two documents.
You can make it easy for editors to define child pages for a given entry. Modify the parent custom type:
This will allow you to add all the children's documents you need for a given parent.
You can use the fetchLinks query option to grab the necessary fields to build the menu.
Alternatively, you can take the group of links and create an array of the documents UID. With this array of UIDs, you can query all the child documents.
To give a Child document a single parent, modify the child custom type:
- Add a single Content Relationship field; this will allow you to specify a "Parent page" for a given child.
To allow a child document to have multiple parents or categories, modify the child custom type:
Add a Group field
Add a Content Relationship field inside the group
This will allow you to add as many parents or categories.
Using this method, you would be able to know which parent(s) a child document has and query all the children of a given parent. To retrieve all the child documents for a given parent, query the child documents by their Content Relationship field. Refer to your favorite technology documentation to learn how to query by Content Relationships.
