If the default editor is unsuitable, you can replace it with a custom editor. For this, implement an editCellTemplate that allows you to configure the replacement editor's appearance and behavior. To change the cell value and, optionally, the displayed value after the editor's value is changed, use the setValue() method of the editCellTemplate. In this demo, the default editors in the Owner and Assignees columns are replaced with the DropDownBox and TagBox components.
