I have been brought in rather late to a project and am trying to get the system stable until I can rewrite it.
We have a grid where I have set in the options
sortable: { mode: "multiple", allowUnsort: true, showIndexes: true }
However, we can only ever sort by a single column. No matter what I've tried, it's always a single column.
What can I look at to start troubleshooting why sorting is always single?
