How to accept and pass extra fields in Properties to inner components

[lightsing]

In React, there's a common pattern that passing unused props to inner components which allows use to override properties like style in inner components.
How to achieve this in yew?

const Button: React.SFC<ButtonProps> = ({ children, className, primary, success, warning, error, disabled, ...other }) => (
  <button
    className={classNames(className, "nes-btn", {
      "is-primary": primary,
      "is-success": success,
      "is-warning": warning,
      "is-error": error,
      "is-disabled": disabled
    })}
    {...other}
  >
    {children}
  </button>
)

You can use .. syntax to pass props. See docs

but I need to accept those props from outer, like in react.
The prop might not exist on ButtonProps but exists on props of button.
