Example for creating rollershutter in flootplan

Hi,
Iam using shellyForHass to open/close my shutter. I want to add this into floorplan but doesnt really have any idea where to start (which css’s, how to configure floorplan.yml to support it, etc…)

I draw some svg but Iam not sure iam going the right direction.

could anyone enlighten me with full example?

Anything new on this one?
