multiSelect : true on that Combo that you have as the editor of that column.
Oh ok. Issue is I cant enable multiselect for now. But since its an array, it will not work with single value. Thank you.
Why can't you add
multiSelect : true?
The value is an array. It's multiple. This is how to edit it.
Right now we dont want to assign two drivers in one shipment. I will tell my team about the limitation.
