how about passing as prop?

[craigcosmo]

this is is hou

export default class Create extends React.Component{
    constructor(){
        super();
        this.state = {
            items: {
                firstName:'',
                lastName: '',
                address: {
                    address1:'',
                    address2:''
                }
            }
        };
    }
    render(){ 
        return(
            <div class="row">
                <Form states = {linkstate} /> 
            </div>
        )
    }
}

how could I access it in Form component?

Ah, no, you use it directly to valueLink as instructed in the #Usage section. In your case, if you want to linkState the state from Create in Form, this might be how:

class Create extends React.Component {
  render() {
    return(
      <div class="row">
        <Form context={this} />
      </div>
    );
  }
}

class Form extends React.Component {
  render() {
    return (
      <form>
        <input valueLink={linkState(this.props.context, 'username')} />
      </form>
    );
  }
}

Feel free to open the issue if you the solution above doesn't do it for you.
