Specifies whether a new line must be added before the headers in fp:tree components.
A new line is added if the value is true.
The fp:defaultnlbeforetreefolders tag is the default value for all the trees in the report. For each of the trees, you can override the default value by using the nlbeforetreefolders="true/false" attribute of the fp:tree tag.
For quick reports, the default value of fp:defaultnlbeforetreefolders is used even if the report template contains fp:tree tags that have different nlbeforetreefolders values.
