News with Topics (Lister Page)
A Lister is a block of code that loads a list of records from a specific view. This code creates a News Lister containing Date, Topic(s), Primary Image (if present) and Summary (in the absence of Summary, it loads partial content of the Body). If you add this code to a page, it can be your "News" page.
