Drupal form with Drag and drop sort order with weight
Based on good article referenced below, I have added some more form items to be used in my case.
When adding more columns or removing, it is important that the number of header items is the same as the number of columns, if you have less header items the drag and drop will not work.
I have added an extra row to be able to add new items. I added an extra item to the database result (//Add new row) and set the id to "new".
In this case I select the latest occurrence of the status types from the database and have added them in a kind of messy why as a #suffix to the last form item and by CCS made it show up below the the form items.
