I’m no longer able to add a child doc type on a document type using Umbraco 15. Is this something that deliberately got removed? I sort of remember hearing that everything is moving to compositions, but I can’t find anything about it. Does anyone know if this is deliberate or not? And, if this…

Document Type inheritance is coming back in Umbraco 16: Content Type inheritance v16/dev ← v16/feature/content-type-inheritance opened 07:17PM - 14 Apr 25 UTC (UTC) …

Think they were deprecated in v14, maybe even v9? Can’t remember. I can definitely recommend compositions instead, a lot more flexible and not as easy to paint yourself in a corner. There seems to be a consensus here as well: https://discord-chats.umbraco.com/t/18800807/when-to-use-inherited-doc-t…

I guess that adds more friction to migrating from older versions of umbraco to v15 Though I have had success in the past with consolidating properties into a composition with the attached below.. though not sure how inherited docs expose the common properties :thinking: if (_contentTypeService.Ge…

Interesting that this functionality has been removed. I don’t remember seeing it being announced as deprecated though? Personally, I tend to use inherited/nested DocTypes when I need a variant of an existing DocType: <a class="lightbox" href="https://forum.umbraco.com/uploads/default/original/2X/4/497174369c79a27133caba511664885ca231e79d.png" data-download-href="https://forum.umbraco.com/uploads/default/497174369c79a27133caba511664885ca231e79d" title="The image presents information about nested DocTypes, explaining their use for creating variants with unique icons, specific properties, and list views, and illustrating this with examples of "Landing Page" and "Content Page" DocTypes, each having further nested options like "News Landing Page," "Blog Landing Page," "News Page," and "Blog Post."

[image] Mike Chambers: I guess that adds more friction to migrating from older versions of umbraco to v15 It will migrate! When upgrading inheritance is preserved as it was before, but you can’t make any new inherited doctypes. I just tested in v13, you can still make inherited doctypes, so …

[image] Owain Jones: Easy enough to do with Compositions too, but I wonder how this will affect the upgrade of v13 sites that used inherited DocTypes? Will they un-nest and lose all of their properties? Will it just break?

Excellent news. I’ll wait another day and pull the release candidate; hopefully the migration from broken 15 to 16 will fix my issue :slightly_smiling_face:
