Note: this block can be used on pages, but it will work best when building posts. You can also use WordPress’s default post meta blocks such as Author Name, Date, and Categories. Example of post content with related posts

In the Block Editor, insert a Post Content with Related block. Enter post copy and images in the content area. Additional blocks can be inserted here; expand the document overview for more control of the blocks inside the Post Content – With Related innerblock.

To add related stories, expand the document overview and inspector panel to select and edit the Related Post innerblocks within the nested Related Post Wrapper block. Upload an image and add post text and URL. Duplicate the Related Post block to insert additional related posts (up to 4 will display in a row at full width). Note: this content will not show up in the edit window, but will on the front end.
