SharePoint List Parent / Child Relationship

SharePointBoost provides functional SharePoint web parts to make it more powerful. It is SharePoint Cascaded Lookup that can enable you to build parent-child relationships between columns in the same list so that data entered in one field filters the options presented in another.You have the freedom to specify the list you want to look up from. It provides a faster way to filter results by specifying a filter column and a parent column. Meanwhile, this will reduce the possibility of making mistakes.

You need connected Web Parts. Have a look at below link.

Hi,

You can create the relationships between list using the Lookup fields.
Parent List -> "News" has fields of -> News Topics|News Regions|ArticleStartDate
Child List -> "Press Release" has fields of -> PageViews |ArticleTags | News Topics|News Regions|ArticleStartDate

So therefore News Topics|News Regions|ArticleStartDate columns are lookup fields/columns.

Also you can create nested content types for the lists.
Parent -> "Discusion" Content type inherited from "Folder" Content type
Child -> "Comments" Content type inherited from "Item" Content type
In this case you can create items/comments inside of the folder/Discussion.
