You can use DevExtreme CLI to create a DevExtreme Angular application with several views and a hierarchical menu (see the live preview):
npx devextreme-cli new angular-app app-name cd app-name npm run start
To add DevExtreme widgets to an existing Angular application, add DevExtreme libraries...
npx -p devextreme-cli devextreme add devextreme-angular
...and then add the required widgets.
DevExtreme CLI also allows you to configure DevExtreme applications and use the Theme Builder features. Refer to the DevExtreme CLI README on GitHub for more information.
