Hi and welcome to our forum.
We are not sure, if we get your idea. Using Work Breakdown view within Merlin Project:
- left side shows the Outline with its columns
- right side shows the Bar Gantt Chart
As you scroll the Gantt horizontally, the Outline information stays to your choosen format, the visible columns, at the same time.
If this does not meet your concept, please give us a bit more details on your idea.
