React Tree List - Popup Editing

TreeList can display a popup edit form. The form can include any fields from the bound data source, regardless of whether the corresponding column is visible in the grid (see the Head column).

To enable this behavior in your application, do the following:

Set editing.mode to "popup".
Set the editing object's allowUpdating, allowAdding, and allowDeleting properties to true.
