And better solution with selected props (aka placeholder for select) is solve it as placeholder not value, cos I cannot write condition with it. Something like if value is null do something. Can I get Context from your components some how? I need focused state class, or isEmpty class etc. Thanks for advice.

Same behavior with disabled props, now tested. Text input must get disabled, this can I writy by myself, but there are need some improvements. :-)

In component MDBSelect, className props is only default classes, not "test". In data array mode works properly.
