In this demo, Dialog mode is enabled for editing by defining editSettings.mode as dialog. You can start editing
by double clicking a row or clicking on toolbar's Edit button, then the currently selected row will be shown on a dialog and
you can change the row values and save edited data to the datasource.
Injecting Module:
Tree Grid features are segregated into individual feature-wise modules. To use editing feature, we need to inject
Editmodule into the services.
More information on the selection configuration can be found in this documentation section.
