# which classes to show
ShowClasses[]
ShowClasses[]=folder
ShowClasses[]=forum
ShowClasses[]=gallery
ShowClasses[]=user_group
ShowClasses[]=article
# ShowClasses[]=frontpage
ShowClasses[]=feedback_form
I have cleared all cache
sudo php bin/php/ezcache.php --clear-all
Yet the article class is not displayed within the administration's <i>dynamic</i> content structure menu.
I reviewed the source code for the dynamic_content_structure menu template and did not notice the usage of the 'ShowClasses' configuration ini variable.
Is there any known reason why my additional custom class entries would not be displayed.
Assuming for the sake of argument that the cache is clearing properly (I deleted the contents of the var/cache and var/(siteaccess)/cache).
It seems that while I thought the global override directory's file, <i>settings/override/contentstructuremenu.ini.append.php</i> would override the admin siteaccess' copy of the same file, <i>settings/siteaccess/starsadmin/contentstructuremenu.ini.append.php</i>
All I had to do was add the classes in the manner Greg recommends to the admin siteaccess settings file, clear cache as Andre recommends and the content structure menu changed.
Thank you to Greg and Andre for their assistance in my search for the answer.
