As discussed above, the first step to create a parent-child relationship with entries is to position the child entry under the parent entry in the list. There are some important considerations to make following this however. If the sole purpose of the parent page is to list child pages then setting the parent entry type to "section" is the best option. Then in the listing options select the source as "entry" and choose the the parent page as the source. If the parent page will have content as well as directing visitors to child pages then it is best to use the entry type of "content" and then add a listing cards module with the same listing settings as above. As of KD 3.5 links to child pages are listed on a parent page under the main site header, it may be preferable to the listing cards if there is content that would justify the more graphical card display.
