Add Dropdown to the Breadcrumb control

Is your feature request related to a problem? Please describe.

I would like to use the Breadcrumb control for navigation, so I can get rid of the TreeView control. The main problem is that TreeView always takes up space.

Describe the solution you'd like

I would like a Dropdown to show on click on BreadcrumbItem. Telerik and DevExpress have such Breadcrumb controls for WinForms.

Additional context

If you are making a file manager, you can just show all the subfolders of the parent folder in the main window - but I am not making a file manager and showing all child nodes of the parent node all the time would take up valuable space.

I am making a note taking app, so I want as much space as possible for the note text, but I still want folder navigation in the same window.
