Add Customize posts edit links to selectively refreshed partials [closed]

Customize Posts recognizes post field partials as defined by selectors in WP_Customize_Posts_Preview::get_post_field_partial_schema() combined by looking for the closest .hentry or .post-{id} elements. So as long as the posts in your editors-picks partials make use of the post_class() function for each element’s container and the other microformats like .entry-title for the child elements, then the post field partials should automatically get added. Take for example my child theme of Twenty Seventeen in how it defines the content-excerpt.php template part and how that template part gets included.
