Add a new issue as a child issue

There are two ways of adding a new issue as a child issue.

1. On the "Show issue" page
Click "Add child issue" link below the issue detail section and choose "Add new child issue" from the menu. The issue added on this page will become a child issue for this issue.
(If the issue is a child issue itself, the new issue will be a child issue for the same parent issue.)

2. On the "Add issue" page
Click "Set parent issue" link above the issue detail section, then put the parent issue key in the field.
(The parent issue must be in the same project.)

You also can choose the parent issue from the list of existing issues by pressing "Select parent issue" button.
