Creating New Work Items
There are two ways to create new Jira Work Items from within Structure: using the Add menu and using Right Click.
Creating a Work Item from the Add Menu
Select an item in the structure. The new work item will be added:
Directly below the selected item
On the same hierarchy level as the selected item
Open the Add menu and select Work Item.

Creating a Work Item with Right Click
Right-click any item in the structure
Select whether you want to place the new item above or below the current item (on the same hierarchy level), or add it as a sub-item

Entering Work Item Details
Enter the information for the new work item:
Name
Projects
Work Type

The Project and Work Type fields may be prepopulated based on the currently selected item. You can overwrite any of these values.

Don’t see your new work item? Make sure you don’t have any Filter generators or Quick Filters that are hiding the new work item
The new work item won’t stay where you added it? Check your Group generators and Quick Groups
