Hello @Thomas_Bro and welcome to our community !

I agree that the component can be more coherent with the rest of our widgets.  
I see nothing against adding the “Select” placeholder. For the null value it allows users to deselect an item from the dropdown, but it certainly can be improved: making the field required would remove the capability to unselect an element.

If these changes correspond to what you were looking for I can create a task for it to be made.

Best regards,

Dogan

Thanks for your reply!  
I was just expected the same behaviour in your documentation. But I think it’s okay for me. Thank you @anon7284711
