Vertical slider

I am integrating blind control from Fibaro, model FGR-222 and everything is working perfectly.

I am using Fibaro-dimmer standard code.

Now I am changing the tiles to show “open” instead of “on” for example.

One thing I wanted was to change the slider to vertical instead of horizontal. How can I do that?

This renders a vertical slider for me on Android:
controlTile(“levelSliderControl”, “device.level”, “slider”, height: 6, width: 4) {
state “level”, action:“setLevel”
}
