I want to move a column to a different position but after dragging it to the desired postion the following message is shown:
You can't reorder while total span sum exceeds 12
The width of the item is 2, the destination has a width of 3, so moving should be possible in my opinion.
Drag and drop isn't always working for other columns too.
My screenshot is only partial. On the left (not visible) is a grid with a width of 6.
Because the grid is high enough, there is plenty visible space on the right for date pickers, buttons, etc. The total width of those items may not exceed 6 and they should be placed on one line.
Now I understand why the error message appears.
Maybe some improvements can be made here to allow filling up the space on the right side of the form more efficiently?
