includeall="1" or includeall="0"
This is a special mode of a factinclude for a folder or factlist. If you set the value 1 to the "includeall", only the facts inside the folder(s) will be included one after another. If there are one or more sub-folders in the folder, you should define the level.
Note: If you use the parameter "includeall", all facts will be displayed with their titles, but they won't be links. In order to change that, you should use "titlelink" in addition.
Important: You can use all options that are available for the includes of facts. For instance you can use the full functionality of the display option in order to have a full list of all facts in the folder(s) with all contained therein information.
