Dropdown element appears below other elements

Hi Thomas, thanks for the nice add on!

I've found an issue using Mushroom Select Card inside an state switch.

The dropdown goes to the back of the other elements making it unusable:

My code for the card is as follows, it doesn't have an off state:

  - type: custom:state-switch
    entity: input_boolean.boiler_automation
    states:
      'on':
        type: custom:mushroom-select-card
        entity: input_select.boiler_auto_time
        layout: horizontal
        primary_info: none
        secondary_info: none
        icon: mdi:clock-time-nine-outline

I tried adding the off state and changing every possible setting but without results. The dropdown card works ok outside of the state-switch.
