====== Navi-Row replacement ======

**Certain lines of a navigation replaced by another content.**

FIXME better translate

With this RT you are able to replace identified  rows in a navigation (NAV_LIST_UL) with specified content from the script. The cement lines or categories are determined by an entry in the field CLASS-defined in category.


This is for example useful when a blank line is required in a vertical navigation.

Insert in  **%%Site structure -> category%%** in the field **CSS class:** the name of the class, in this example: "separator". \\
