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. Furthermore you can use all options that are available for the includes for the facts.
