The default structure is automatically selected when the user opens Structure Board for the first time. It is also shown when a user views the Structure widget from an issues page, if the Auto-switch option is set to default structure.
You can change the default structure for the entire Jira instance, as well as for specific projects.
Changing System-level Default Structure
The system-level default structure is used when no other structure has been selected or the Auto-switch option is set for issue pages (and a project-level default structure has not been specified).
Open the Administration | Structure | Defaults menu.
In the System Default Structure section, click Change.
Select the default structure and click Apply.
Make sure users have View permissions to the default structure. Users without view permissions will receive an error when the default structure should be displayed.
Changing Project-level Default Structure
You can select a default structure for specific projects.
Open the Administration | Structure | Defaults menu.
Locate the project in the Project Default Structures section and click Change. If you can't find the structure, un-check the Show only projects with overridden default structure checkbox.
Select a structure and click Change.
Or, select Use system default to remove the project-level default.
Project administrator can also change the project-level structure from the Structure tab on the project administration page, or from the options pop-up window on the Structure tab on the user's project page.
