ColumnEdit
columnEdit is used to specify a column to which the parent nodes are displayed.
If this property
is empty, it is the first column which is treated as the Edit column.
In the example below, we swapped the Child and Parent node columns in the form layout and run the application without adding any new properties:
As can be seen, the branches names and descriptions also swapped.
When the ColumnEdit property is set to "parentnode" (the ID of the column with parent nodes names), the right column becomes the parent nodes holder
