Lists and detail pages
You want to show always the latest news? With OpenCms you can collect contents in a list - for example showing teasers for the 10 latest news articles. Whenever a new news is published, the list is automatically updated. Moreover, editors can directly edit, add or delete news in the list.
Having teasers for the news articles in the list, you may want to provide each whole news on a specific page. With OpenCms you can add a detail page for news articles and link to it from the list. One detail page is sufficient for showing the detailed information for all news contents under nicely generated URLs.
Of course, you can use the mechanism for other content types as well, e.g., event lists, blogs, .... And your lists can support many advanced features like filters (for categories, full text search, ...), pagination or various sort options.
OpenCms 11 even provides a content type for lists in the core, that supports all the advanced features and eases list management via a dedicated workplace app.
