Craft 5: How can I reference the top-level "Entry" from multi-nested Matrix entry types?

[proimage]

I've got a couple of Matrix fields, a "Page Builder" field which only has "Container" entry types, and a "Content Blocks" field which has all the usual suspects (Heading, Text, Buttons, Images, etc). The hierarchy looks like this:

Site -> "Pages" section -> "My Entry" entry -> "Page Builder" field -> "Container" entry type -> "Content Blocks" field -> "Heading" entry type.

If I want to output the slug of "My Entry" (myEntry) from inside the "Heading" entry type, how can I do that? The owner variable just seems to reference the "Container", not the "My Entry" entry. Repeated instances of owner, such as entry.owner.owner.slug, seem to work, but I can't know how many repetitions I'm going to need...

You're looking for the "root owner", e.g.

{% set rootOwner = entry.rootOwner %}

{{ rootOwner.slug }}

Ahh, perfect, thanks!
