Thank for your help,

>>> 
>>> 1. Dynamic functions ("Content without content"): You may see this content like a formatter configuration that you don't have to backup with a content type you created. The only drawback (I see) is that all dynamic functions will appear under "Dynamic function" in the add wizard of the page editor. Hence, all functionality that is dynamic will appear in the same "box". The default Mercury template uses various dynamic functions. You find them under "Advanced elements" in the add wizard.
>>> 
>>> 
>>> 2. Function detail pages: I essence, it's just a way to make a page linkable by a special name. Forget about the additional configurations that will make the function appear on the function detail page (the container.info property), they barely work for nested containers, but you can place the function by hand on the function detail page.
>>> 
>>> Here's an example:
>>> 
>>> Assume in your template you have a footer always adding a "Privacy" link. But, depending on the site or the locale you are in, the link should point to different urls. That's a good example for a function detail page.
>>> 
>>> In your template JSP when you add the link, just use ${cms.functionDetail['privacy']} as link target.
>>> 
>>> And in the sitemap configurations of your (sub-)sites add the detail page 'function at privacy' pointing to the (sub-)site specific URL. If you added the function as named function in the module (see https://documentation.opencms.org/opencms-documentation/template-development/dynamic-functions/function-detail-pages), you may also do this via the sitemap editor by adding a function page. But this is optional, adding it just by hand in the .config file is good as well.
>>> 
>>> The default demo of the current OpenCms version uses a function detail page (that is not configured as named) for the search page. You find a detail page 'function at Search page' in the sitemap configurations.
