Description

In this example, we create a custom state that shows a chart with an overview of all objects in the system. The resulting donut doughnut chart is clickable to drill down into the specific object types.

...

Use a CLI command to generate a state component with a custom name and sidebar link. The link appears in the navigation menu on the left. (sidebar-navigation = default)

Description

This example provides two new states. The first one shows the search result list in full screen, out of outside the usual client context. The second one shows the content preview of an object, also in full screen.
