I have 3 post types:
“A”: Phòng (Room)
“B”: Lưu trú (Resort)
“C”: Quảng cáo (Asvertising)
A is in one-to-many with C
B is in one-to-many with A, C

*Tell us what you are trying to do?
I’m creating a view of C at B page. In view search and view output, I put fields from both A and C. But in front-end, the view search only shows choosing fields from C, but not A.

*Is there any documentation that you are following?

*Is there a similar example that we can see?

*What is the link to your site?

Hello,

I assume you are using one-to-many relationship between post types A and C, in the single C post( Loop of view of C ), you can display the related A post information directly, see our document:

If you need more assistance for it, please provide your website credentials in below private message box, I can setup a demo for you.

Thanks for the details, Toolset Blocks plugin is using WordPress built-in class WP_Query to query posts, you can only filter the results by fields of current post type(C), you can not filter the result by fields of other parent post type(A), so it is expected result, the filter won't be able to work.

And you might consider other workaround, for example, you can filter the child C posts by parent A post title, see our document:
