Problem: I have a View that displays posts. I would like to display only those posts in a specific subcategory.
Solution: Use the Query Filter panel to add a taxonomy term Query Filter. If the View is built in the Block Editor, you must select the top-level View block. You can use the Block Navigator menu if necessary to select the correct block. Then Query Filter options will appear in the Content Selection block configurations panel. If the View is built in the legacy Views editor, you can expose the Query Filter panel in Screen Options.
I have a custom post type and the content for it is created by different individual. I would like to create view or a content template that only shows their individual posts .
Solution:
You can setup a post view, filter by post's author is current logged-in user.
