Possible to collapse RadzenPanelMenu like standard NavMenu?

Is it possible to collapse the RadzenPanelMenu like the standard Blazor NavMenu? If so, how? Thanks.

You can check how this is done in the Radzen demo application: radzen-blazor/MainLayout.razor at master · radzenhq/radzen-blazor · GitHub

That bit of code references; RadzenSidebar, RadzenSidebarToggle, RadzenHeader, and RadzenBody tags among others not included anywhere in your Blazor components page: https://blazor.radzen.com/ . Nor does it show up anywhere in the documentation page: Overview (Blazor) .

Why is that?
