Problem: I have a View that displays a list of posts. I would like to order the list by some criteria within the posts.

Solution: Use the Ordering panel sidebar of the main View settings when you select the top-level View block in the block editor to change the sort order criteria. You can choose a post date criteria or a custom field criteria, and set primary and secondary sorting options for the View.
