As far as I remember ERNavigationMenu has a limit of three levels. I have not
looked into it extensively to see where the limitation is, but I remember a
suggestion to use the ModernNavigationMenu when you needed more than 3 levels.
Have you considered moving your navigation widget somewhere else outside the
navigation menu structure? For example in a header or above a repetition?? If
you remember the old NeutralLook stuff, the pagewrapper contained something
like you are trying to create.
