Sub-task type can't be created in Structure

Problem

When I click ‘Add’ or press Enter to create a new issue in my structure, I cannot select the Sub-task type; it’s not on the list.

Solution

This behavior is as expected - issues of the Sub-task type cannot exist independently from their parent issues, so it’s not possible to create them the same way as any other standalone issue type. The same behavior exists in Jira: when you click the Create button at the top, Sub-tasks are missing from the list there as well, for the same reason.

Sub-tasks can be created in a structure in two ways:

1. You can use the Jira actions menu: on the right side of any issue in the structure, you can click the button with three dots to display the menu, and then click the ‘Create sub-task’ option.

2. If a parent issue already has at least one sub-task underneath it in a structure, and you want to create more Sub-tasks in it, you can place the focus on the existing sub-task, press Enter, select the ‘Copy from’ option in the panel window, type in the summary of the new sub-task, and click Done. As a result, all data, expect for the summary, will be copied from an existing sub-task.
