I'm trying to display Sibling Posts of a current child post in a Views Block. I have a test site using Astra and have set up Post Types "Trail" (Parent) and "Section" (Child). They are called 'LAW' and 'Walk' respectively in the test site. I have set a one-to-many relationship between LAW->Walk.

I can show all children on a LAW page: hidden link

I can show the parent on a Walk page: hidden link

What I want to show is all the siblings of a Walk, on the Walk page - using Blocks workflow. So if I'm looking at XYZ walk 1, I can see XYZ walk 2, XYZ walk 3...

I have had a look at the following link but it uses the old Views/Layouts workflow;

Is it possible in Blocks?

Thank you for your feedback and for the access information.

I run a test on my local setup where I have a parent-child relationship between States and Cities, and I have the following data:
State: Marrakesh-Safi has two:
-- City: Marrakesh
-- City: Safi
And I was able to show Safi, a sibling of Marrakech within for parent state, inside Marrakesh page, check this image hidden link

I followed these steps:
1. Create an unassigned Content Template, this template must not be assigned to any post type.
2. Add a new View Block to show the siblings.
2.1. Choose the post type "Section/Walk", and add a relationship Query Filter for the parent "Trail/law" according to "the current post in the loop".
2.2. Add the field that you want to show for the sibling (title, etc.)
3. Create a Content Template for the child post type "Section/Walk".
3.1. Create a Classic Block.
3.2. Use the "Fields & Views" button to insert the unassigned Content Template that you have created on 1.
3.3. In the "Post selection" tab choose the "A post related to the current post, set by a Types relationship" and your relationship. Check this image hidden link

I hope this helps. If you found any troubles, I have already set your next reply as private to share access to your website, so I can check it closer. Please make a database backup before sharing credentials.

You did not get the expected screen on 3.3, because you have added a view(LAW Walk Siblings View) on 3.2 instead of adding the unassigned content template(LAW Walk Siblings).

For debugging I removed some blocks from the templates. But I was able to fix it by removing the view from the classic block and adding the content template, then I was able to select the law/walks relationship.
Check my result on this screenshot hidden link

I hope this helps. And I remain at your disposal.

Strange. I was sure I added the content template but must have done as you said. Thanks for helping out!
