includeall="1" or includeall="0"

This is a special mode for a factinclude for a folder. If you set a value 1 to the includeall, only the facts inside the folder(s) will be included one after the other. If there are one or more sub-folders in the folder, you should define the level.

Note: If you use includeall all facts will be displayed with their titles, but they won't be links. In order to change that, you should use additionaly titlelink.
