How to set a default value in react-select

I have an issue using react-select. I use redux form and I've made my react-select component compatible with redux form. Here is the code:

const MySelect = props => (
    <Select
        {...props}
        value={props.input.value}
        onChange={value => props.input.onChange(value)}
        onBlur={() => props.input.onBlur(props.input.value)}
        options={props.options}
        placeholder={props.placeholder}
        selectedValue={props.selectedValue}
    />
);

and here how I render it:

<div className="select-box__container">
    <Field
    id="side"
    name="side"
    component={SelectInput}
    options={sideOptions}
    clearable={false}
    placeholder="Select Side"
    selectedValue={label: 'Any', value: 'Any'}
    />
</div>

But the problem is that that my dropdown has not a default value as I wish. What I'm doing wrong? Any ideas?

Solution 1:

I guess you need something like this:

const MySelect = props => (
<Select
    {...props}
    value = {
       props.options.filter(option => 
          option.label === 'Some label')
    }
    onChange = {value => props.input.onChange(value)}
    onBlur={() => props.input.onBlur(props.input.value)}
    options={props.options}
    placeholder={props.placeholder}
  />
);

Solution 2:

I used the defaultValue parameter, below is the code how I achieved a default value as well as update the default value when an option is selected from the drop-down.

<Select
  name="form-dept-select"
  options={depts}
  defaultValue={{ label: "Select Dept", value: 0 }}
  onChange={e => {
              this.setState({
              department: e.label,
              deptId: e.value
              });
           }}
/>

Solution 3:

If you've come here for react-select v2, and still having trouble - version 2 now only accepts an object as value, defaultValue, etc.

That is, try using value={{value: 'one', label: 'One'}}, instead of just value={'one'}.

Solution 4:

I was having a similar error. Make sure your options have a value attribute.

<option key={index} value={item}> {item} </option>

Then match the selects element value initially to the options value.

<select 
    value={this.value} />

Solution 5:

Extending on @isaac-pak's answer, if you want to pass the default value to your component in a prop, you can save it in state in the componentDidMount() lifecycle method to ensure the default is selected the first time.

Note, I've updated the following code to make it more complete and to use an empty string as the initial value per the comment.

export default class MySelect extends Component {

    constructor(props) {
        super(props);
        this.state = {
            selectedValue: '',
        };
        this.handleChange = this.handleChange.bind(this);

        this.options = [
            {value: 'foo', label: 'Foo'},
            {value: 'bar', label: 'Bar'},
            {value: 'baz', label: 'Baz'}
        ];

    }

    componentDidMount() {
        this.setState({
            selectedValue: this.props.defaultValue,
        })
    }

    handleChange(selectedOption) {
        this.setState({selectedValue: selectedOption.target.value});
    }

    render() {
        return (
            <Select
                value={this.options.filter(({value}) => value === this.state.selectedValue)}
                onChange={this.handleChange}
                options={this.options}
            />
        )
    }
}

MySelect.propTypes = {
    defaultValue: PropTypes.string.isRequired
};
