Accepted answer

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}
  />
);

You can simply do this as:

In react-select, initial options value

const optionsAB = [
  { value: '1', label: 'Football' },
  { value: '2', label: 'Cricket' },
  { value: '3', label: 'Tenis' }
];

API giving only:

apiData = [
  { games: '1', name: 'Football', City: 'Kolkata' },
  { games: '2', name: 'Cricket', City: 'Delhi' },
  { games: '3', name: 'Tenis', City: 'Sikkim' }
];

In react-select, for defaultValue=[{value: 1, label: Hi}]. Use defaultValue like this example:

<Select
  isSearchable
  isClearable
  placeholder="GAMES"
  options={optionsAB}
  defaultValue={{
    value: apiData[0]?.games , 
    label: (optionsAB || []).filter(x => (x.value.includes(apiData[0]?.games)))[0]?.label
  }}
  onChange={(newValue, name) => handleChange(newValue, 'games')}
/>

You can use this in Java normal also.

In react-select if you want to define for the custom label, try this.

  <Select
    getOptionLabel={({ name }) => name}
  />

If your options are like this

var options = [
  { value: 'one', label: 'One' },
  { value: 'two', label: 'Two' }
];

Your {props.input.value} should match one of the 'value' in your {props.options}

Meaning, props.input.value should be either 'one' or 'two'

To auto-select the value of in select.

enter image description here

<div className="form-group">
    <label htmlFor="contactmethod">Contact Method</label>
    <select id="contactmethod" className="form-control"  value={this.state.contactmethod || ''} onChange={this.handleChange} name="contactmethod">
    <option value='Email'>URL</option>
    <option value='Phone'>Phone</option>
    <option value="SMS">SMS</option>
    </select>
</div>

Use the value attribute in the select tag

value={this.state.contactmethod || ''}

the solution is working for me.

  1. Create a state property for the default option text in the constructor
    • Don't worry about the default option value
  2. Add an option tag to the render function. Only show using state and ternary expression
  3. Create a function to handle when an option was selected
  4. Change the state of the default option value in this event handler function to null

    Class MySelect extends React.Component
    {
        constructor()
        {
            super()
            this.handleChange = this.handleChange.bind(this);
            this.state = {
                selectDefault: "Select An Option"
            }
        }
        handleChange(event)
        {
            const selectedValue = event.target.value;
            //do something with selectedValue
            this.setState({
                selectDefault: null
            });
        }
        render()
        {
            return (
            <select name="selectInput" id="selectInput" onChange={this.handleChange} value= 
                {this.selectedValue}>
             {this.state.selectDefault ? <option>{this.state.selectDefault}</option> : ''}
                {'map list or static list of options here'}
            </select>
            )
        }
    }

Use defaultValue instead of selected

If you want to hide the value from the menu, use hidden:

<option defaultValue hidden>
   {'--'}
</option>
{options.map(opt => (
    <option key={opt} value={opt.replaceAll(/[,'!?\s]/gi, '')}>
       {opt}
    </option>
))}

Wanted to add my two cents to this, using Hooks,

You can subscribe to props in the DropDown

import React, { useEffect, useState } from 'react';
import Select from 'react-select';

const DropDown = (props) => {
  const { options, isMulti, handleChange , defaultValue } = props;
  const [ defaultValueFromProps, setdefaultValueFromProps ] = useState(undefined)

  useEffect(() => {
    
    if (defaultValue) {
      setdefaultValueFromProps(defaultValue)
    }
  }, [props])
  
  const maybeRenderDefaultValue = () => {
    if (defaultValue) {
      return { label: defaultValueFromProps, value: defaultValueFromProps }
    } 
  }
  return (
    <div>
      <Select 
        width='200px'
        menuColor='red'
        isMulti={isMulti} 
        options={options} 
        value={maybeRenderDefaultValue()}
        clearIndicator
        onChange={(e) => handleChange(e)}
      />
    </div>
  )
}

export default DropDown;

and then in the parent component either pass the initial value or changed value from state

<DropDown options={GenreOptions} required={true} defaultValue={recipeGenre === undefined ? recipe.genre : recipeGenre} handleChange={handleGenreChange}/>

Then if it's a fresh form (no default value) you won't have to worry since the useEffect will ignore setting anything

2022 example with Redux react with useSelector

As of 2022 there is a defaultValue option in react-select. Please note that if you are using getOptionLabel, and getOptionValue, you need to make your default value match those option params you set....

for example


const responder = useSelector((state) => state.responder)



<Select
              name="keyword"
              required={true}
              className="mb-3"
              styles={customStyles}
              components={animatedComponents}
              closeMenuOnSelect={true}
              options={keywords}
              defaultValue={responder ? responder[0]?.responder?.keyword?.map((el) => { return {title: el.title, _id: el._id}}): ""}
              getOptionLabel={({title}) => title}
              getOptionValue={({_id}) => _id}
              onChange={(_id) => setUpload({...upload, keyword: _id})}
              isMulti
              placeholder="select Keywords"
              isSearchable={true}
              errors={errors}
              innerRef={register({
                required: "Add your Keyword"
              })}
            />


rather than setting your defaultValue with {label: "this", value: "that}

I needed to set mine with defaultValue({title:"this", _id: "that"})

If you are not using redux-form and you are using local state for changes then your react-select component might look like this:

class MySelect extends Component {

constructor() {
    super()
}

state = {
     selectedValue: 'default' // your default value goes here
}

render() {
  <Select
       ...
       value={this.state.selectedValue}
       ...
  />
)}

I'm using frequently something like this.

Default value from props in this example

if(Defaultvalue ===item.value) {
    return <option key={item.key} defaultValue value={item.value}>{plantel.value} </option>   
} else {
    return <option key={item.key} value={item.value}>{plantel.value} </option> 
}

score:1

Use <select value={stateValue}>. Make sure that the value in stateValue is among the options given in the select field.

score:1

couple of points:

  1. defaultValue works for initial render, it will not be updated on sequential render passes. Make sure you are rendering your Select after you have defaultValue in hand.

  2. defaultValue should be defined in form of Object or Array of Objects like this: {value:'1', label:'Guest'}, most bulletproof way is to set it as item of options list: myOptionsList[selectedIndex]

score:2

I just went through this myself and chose to set the default value at the reducer INIT function.

If you bind your select with redux then best not 'de-bind' it with a select default value that doesn't represent the actual value, instead set the value when you initialize the object.

You need to do deep search if you use groups in options:

options={[
  { value: 'all', label: 'All' },
  {
    label: 'Specific',
    options: [
      { value: 'one', label: 'One' },
      { value: 'two', label: 'Two' },
      { value: 'three', label: 'Three' },
    ],
  },
]}
const deepSearch = (options, value, tempObj = {}) => {
  if (options && value != null) {
    options.find((node) => {
      if (node.value === value) {
        tempObj.found = node;
        return node;
      }
      return deepSearch(node.options, value, tempObj);
    });
    if (tempObj.found) {
      return tempObj.found;
    }
  }
  return undefined;
};

                    isClearable={false}

Use defaultInputValue props like so:

<Select

   isClearable
   onChange={handleChanges}
   options={colourOptions}
   isSearchable="true"
   placeholder="Brand Name"
   defaultInputValue="defaultInputValue"
/>

As I followed all the answers above, it came to my mind, I should write this.

you have to set the prop value, not the DefaultValue. I spent hours by using this, read the documentation, they mentioned to use the DefaultValue, but it is not working. correct way would be,

options=[{label:'mylabel1',value:1},{label:'mylabel2',value:2}]
seleted_option={label:'mylabel1',value:1}

<Select
options={options}
value={selected_option}/>

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
};

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} />

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'}.

score:99

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
              });
           }}
/>
