Let's say we want to see child items for the postcode, city and county.
We should provide links definition in the /atg/remote/content/browse/ContentBrowseHierarchy.xml
Insert the following into the xml so that Merchandising will know parent/child for each item:
<links id="postCodeLinks" parent-type="/cognity/estore/repository/AddressBookRepository:addressBookPostCode">
<list-definition allow-circular-reference="false" visible="true" retriever="property" set-site-context-on-drilldown="false" allow-load="true" show-header="conditionally" id="postCodeChildStreets" show-count-on-header="false" allow-drilldown="true" child-type="/cognity/estore/repository/AddressBookRepository:addressBookStreet" show-count-on-children="false">
<retriever-parameter name="propertyName" value="parentPostCodeId"/>
<retriever-parameter name="reverseLink" value="true"/>
</list-definition>
</links>
<links id="cityLinks" parent-type="/cognity/estore/repository/AddressBookRepository:addressBookCity">
<list-definition allow-circular-reference="false" visible="true" retriever="property" set-site-context-on-drilldown="false" allow-load="true" show-header="conditionally" id="cityChildPostCodes" show-count-on-header="false" allow-drilldown="true" child-type="/cognity/estore/repository/AddressBookRepository:addressBookPostCode" show-count-on-children="false">
<retriever-parameter name="propertyName" value="parentCityId"/>
<retriever-parameter name="reverseLink" value="true"/>
</list-definition>
</links>
<links id="countyLinks" parent-type="/cognity/estore/repository/AddressBookRepository:addressBookCounty">
<list-definition allow-circular-reference="false" visible="true" retriever="property" set-site-context-on-drilldown="false" allow-load="true" show-header="conditionally" id="countyChildCities" show-count-on-header="false" allow-drilldown="true" child-type="/cognity/estore/repository/AddressBookRepository:addressBookCity" show-count-on-children="false">
<retriever-parameter name="propertyName" value="parentCountyId"/>
<retriever-parameter name="reverseLink" value="true"/>
</list-definition>
</links>
