Jira determines which screen scheme to use for an issue type by establishing an association between screen schemes and issue types. Each issue type can have only one screen scheme associated with it. However, each screen scheme can be associated with more than one issue type.

Perform the following steps to add a new association:

1. Browse to the Configure Issue Type Screen Scheme page for the issue type screen scheme you wish to configure.
2. Click on the Associate an Issue Type with a Screen Scheme button.
3. Select the issue type to add an association.
4. Select the screen scheme to be associated with the issue type.
5. Click on the Add button to create the association:

As shown in the preceding screenshot, the Story, Task, and Bug issue types are explicitly associated with PM: Project Management Story Screen Scheme, PM: Project Management Task Screen Scheme, and PM: Project Management Bug Screen Scheme, respectively. All other issues types, such as Sub-task, will be associated with the default PM: Project Management Screen Scheme.
