BCMS Sitemap Portlet and templates

# the sitemap portlet 
# takes two inputs via the form - a top level section to map beneath (defaults to root section) and a list of sections to exclude from map

class SitemapPortlet < Portlet

#  render_inline false

  def render
    top_level = self.section
    if top_level.empty? or top_level.nil?
      @section = Section.find_by_root(true)
    else
      @section = Section.find_by_name(top_level)
    end

    @excluded_sections = []
    if self.exclude
      exclusion_list = self.exclude.split(",")
      exclusion_list.each do |section_name|
        section = Section.find_by_name(section_name.strip)
        @excluded_sections << section if section

# Patrick - please note that this template is in Renshi (a templating language I wrote, you can find it on my github profile or install the gem). 
# It should be very easy to map into ERB. Sorry, didn't have time to do so.
