I have successfully been able to get the default sortable list working, this works without any issues,  however it doesn’t quite fit my needs.

I need a similar list, however with 3 distinct columns (rows will contain linked data)... ideally, reordering by selecting and moving any item in any of the 3 columns.

Can this be achieved ??...assuming so, I am looking for advise on how the default code could be modified

 Thank you
