The Tree Grid supports CRUD operations. This CRUD operations can be configured in Tree Grid using editSettings. Also, it has different modes to manipulate the datasource.
Row
          Cell
          Dialog
          In this demo, Row mode is enabled for editing by default. You can start editing any row by double clicking on it or clicking on toolbar’s Edit button, then the currently selected row will be changed to edited state. You can change the row values and save edited data to the datasource.
          We have also provided an option in property panel to select the edit
          mode as Cell or Row to change mode of editing.
        
Injecting Module:
          Tree Grid features are segregated into individual feature-wise
          modules. To use editing feature, we need to inject
          Edit module into the services.
        
          To use indent and outdent feature, we need to inject
          RowDD module into the services.
