I want to hide these sections , but every person can change the workflow. So how to hide this?
The Approval Workflow forms are InfoPath forms that can be modified using Infopath Designer.
To modify the form do the following:
- Open the SharePoint Designer
- Connect to your Site.
- Got to Workflow > Click on the Approval Workflow.
formsSection,> Click on the form to open and edit it with InfoPath.
- Now, you can remove the CC field or hide it as mentioned at Hide a control based on values on the form
