 You can create a standalone component by setting the `standalone` property to `true`. The standalone component is enabled by default in Angular v17 and later. You can disable the standalone component by setting the `standalone` property to `false` in the `@Component` decorator of the component. If you disable the standalone component, you need to import the component in the `app.module.ts` file. If you created a non-standalone component, you will see no standalone property in the `@Component` decorator.
