1T Dropdown - Borders changes not applying (set state)

Hi everyone (and @eli),

I’m using 1T dropdown for several parts of my app and on forms.
When using in forms, I want to indicate that their is an error or that the value in the dropdown is missing.

For that, I have a state “erreur” with some conditional formating on borders. But I apply the state, the conditional formating doesn’t apply on borders.

Am I missing something? Is there a bug in the plugin?

Thanks.
