Editing by Dragging and Dropping
Currently, the dragging and dropping of items (
editable.move = true
andeditable.move.reorderable
) is not supported with the incell edit mode of the TreeList because the draggable functionality prevents themousedown
event. As a result, thechange
event of the editor input does not fire, which in turn prevents the MVVM binding from saving the updated value. To work around this problem, refer to this GitHub issue.
When the editable.move
option is set to true
, the user can drag and drop the rows and the TreeList internally updates the parentId
field. Setting the editable.move.reorderable
property to true
enables users not only to move items to a different level in the hierarchy but also allows users to reorder items within a particular hierarchy level.
To persist the new hierarchy, configure the TreeList data source for CRUD operations and set transport.update
as a bare minimum. For a runnable example, refer to the demo on editing by dragging and dropping the rows of the TreeList.
The following example demonstrates how to enable the batch data source and the editable move configuration.
