I have defined the rule application setting, added a category, and filled out the history tab for each. The box that says to "hide the display in app studio" is unchecked. The rules are all in a ruleset within the application definition.
@stevenh5 many thanks for bringing up this subject.
We would encourage you to use the 'Contact Us' link on any article if you believe that the articles can be enhanced in any way,.
I have checked our Pega 8.8 documentation and there is no mention of the toggle setting there either. Perhaps you can use the 'Feedback' button on the top right to also provide the details which you believe to be missing there?
Thanks @MarijeSchillern. I submitted feedback on that article. This is a great feature to not only organize application settings in one place, but empower citizen developers or other power users. Unfortunate about the missing documentation.
