You would like to change which menu options are available for activities, such as removing the "Budget" tab or "Documents" tab.
From any DevResults page, go to the Administration menu and click on "Program Settings".
Under Program Settings, find the Features section. Check or uncheck boxes next to the activity menu tabs to either show or hide these features. Click "Done". Now when you visit an activity's page, you will only see the activy menu tabs that are checked on the Program Settings page.
