Material-ui: Can't get attributes of material-ui SelectField in react

[da2018]

I'm using SelectField of material-ui for my react project. I have tried many ways from this answer Can't get the target attributes of material-ui select react component .

But they don't work.My target.id always equals "" How can I get the attributes (like id).

Here is my code:

constructor(props) {
    super(props);
    this.state = {
        form: {
            resident_city: ''

        },
        ret_code: '',
        ret_msg: ''
    };
    this.handleList = this.handleList.bind(this);
}

handleList(event, index, value) {
    event.persist()
    const field = event.target.id;
    const form = this.state.form;
    form[field] = value;
    console.log(event, value)
    this.setState({
        form
    });
    console.log(form);
}


        <form>
            <SelectField
                style={style}
                id="city"
                value={this.state.form.resident_city}
                onChange={this.handleList}
                maxHeight={200}
            >
                {cities}
            </SelectField>
        </form>

I tried to use SelectField without form,and I still can't get the id attributes.It is really confusing me.

I read this issus Identify which [SelectField] [DropDownMenu] fired onChange and his question on stackoverflow Identify which [SelectField] [DropDownMenu] fired onChange

Although the answer is a way to solve this problem,but I want to know how can I get id attribute like Textfield name?

My question on stackoverflow Can't get attributes of material-ui SelectField in react

Any help would be great appreciate.

@TracyDa
The link you added helped me to fix the issue. I don't think there is another good solution to this.

I tried to get to the parent element by doing event.target.parentElement.parentElement but that didn't work either.

On the main component you define a prop name for select the form component let say your city component is called : cityForm

in your cityForm component

  handleSelectChange(e, index, value) {
        this.props.selectChange(e, index, value, this.props.cityName);
  }

render() { 
return (
       <SelectField
                style={style}
                value={this.props.city}
                onChange={this.handleSelectChange}
                maxHeight={200}
            >
                {cities}
            </SelectField>
);
}
}

In your main comp you will have let say (code is cutted some part omitted)

 handleSelectChange(e, index, value, name){
      this.setState({
      [name] : value,
    });
  }

render(){ 
 return (
  <cityForm cityName = "city1"  city={this.state.city1} selectChange={this.handleSelectChange}/>
  );
 }
}

Im building a dynamic form generator and it did the trick for me =) no need to pass an argument directly in the bind.
