This sample demonstrates the usage of context menu in Tree Grid component. Right click anywhere on the Grid to view context menu.
Tree Grid has an option to show the custom context menu when right click on it. To configure the custom items in context menu,
you should define custom item in contextMenuItems.
In this demo, Custom Context Menu feature has enabled by defining the custom context menu Expand the Row and
Collapse the Row for the parent nodes in contextMenuItems property.
Injecting Module:
Tree Grid features are segregated into individual feature-wise modules.
To use context menu feature, we need to inject ContextMenu module into the services.
