Split mode allows you to work with two structures side by side. To enable, click the Split button in the Structure toolbar.
The second structure is fully functional and offers the same functions as the main structure. For example, you can open other structures, customize your view, create filters, and search with JQL or text.
If you have Structure.Gantt installed, the secondary panel can also be used to plan work and resource allocations on your Gantt chart.
Display or hide shared items
Select the Hide/Show icon to toggle the display of work items in the secondary structure that are also present in the main structure. This is useful if you need to quickly compare that the items in your structure were also found in a search in the secondary panel.
Copying items between panels
Drag items from one structure to another to copy that item. You can also select Cut or Copy to move an item to the clipboard, then Paste it in the other structure.
Press the Ctrl key (⌥ key on MacOS) while dragging an item to move the item instead of copying it. This deletes the item from the source structure and recreates it in the target structure.
Resizing the Panels
You can change the size of each panel (giving more space to one of the structures) by the dragging the separating border between the panels.
