Is there a way to configure a new Instance of the CMSPortlet
that will browse a given CMS directory or is it only for viewing a given page?
As it is provided, the CMS portlet only show a page.
but you can look at how it is working, and at the API to get the folders and files from the CMS, to build your own presentation of folders.
look also at the catalogPortlet : change the content with some folder of the cms, instead of the pages of the portal (same général portlet that show a list of things, and navigation...).
