I found a solution using css styles in mod-card:
type: 'custom:mod-card'
style:
hui-entities-card$hui-input-select-entity-row$: |
state-badge {
width: 0px;
}
'hui-entities-card$hui-input-select-entity-row$ha-paper-dropdown-menu$paper-input$#container$': |
div.floated-label-placeholder {
line-height: 0px;
}
Changing the width in “state-badge” to 0px gets rid of the icon box and stretches the input select line over the icon. You still have to set your icon to ’ ’ to remove the image.
Changing the line-height in “div.floated-label-placeholder” to 0px gets rid of the entity name box above the input select line and centers the line vertically in the container. Set the name to [] and you can be fully rid of that part as well.
