Structure can be enabled for any selection of the JIRA projects, or for none of them. (In the latter case no one can use Structure.)
By default, Structure is enabled for all projects. To limit users' exposure to Structure, pick specific projects to be enabled for Structure.
To select which projects are enabled for Structure:
- Navigate to Administration | Structure | Configuration.
- Click Enable/Disable Structure in Projects.
- Select whether Structure should be available for all projects or for selected projects.
- In the latter case, change the projects list in the Selected Projects list by selecting one or more projects and using Enable and Disable buttons.
- Click Apply when done.
- In case you have disabled some projects that are already used in a structure (a structure contains issues from that project), you'll be given a warning. You can opt to Proceed with Changes or cancel.
- If you proceed and disable a project that has issues in some structures, those structures will appear to the users without those issues.
- If you later enable that project back - the issues will reappear where they were (all structure changes taken into account).
