Tell us what you are trying to do?
I am trying to create a view where for every 'event' so that view also shows it's 'pictures'. Both events and pictures are cpt's, and they are in a one-to-may relationship; one event-multiple pics.
Is there any documentation that you are following?
I watched the video's twenty times but I am never getting the dialog box that is in your documentation. I put some screenshots. I can only select the radio button for pictures, but it does not open this secondary radio button list.
Is there a similar example that we can see?
I have created a test page and a test content template to try to achieve this. Feel free to play with them.
What is the link to your site? hidden link
When I create a admin user for you, how do I get the username and pass to you?
The problem is that you needed to add the view to display the related pictures to the content template of the Event as you can see I did below. hidden link
My issue is resolved now. Thank you!
Your last remark did the trick : "An important notice is that the view must always be placed on the template of the Parent/child custom post type."
