FAQ

How do I make the input dynamically grow in size?

Install react-input-autosize and change the renderInput prop to:

function autosizingRenderInput ({addTag, ...props}) {
  let {onChange, value, ...other} = props
  return (
    <AutosizeInput type='text' onChange={onChange} value={value} {...other} />
  )
}
How do I add auto suggestion?

Use react-autosuggest and change the renderInput prop to something like:

function autosuggestRenderInput ({addTag, ...props}) {
  const handleOnChange = (e, {newValue, method}) => {
    if (method === 'enter') {
      e.preventDefault()
    } else {
      props.onChange(e)
    }
  }

  const inputValue = (props.value && props.value.trim().toLowerCase()) || ''
  const inputLength = inputValue.length

  let suggestions = states().filter((state) => {
    return state.name.toLowerCase().slice(0, inputLength) === inputValue
  })

  return (
    <Autosuggest
      ref={props.ref}
      suggestions={suggestions}
      shouldRenderSuggestions={(value) => value && value.trim().length > 0}
      getSuggestionValue={(suggestion) => suggestion.name}
      renderSuggestion={(suggestion) => <span>{suggestion.name}</span>}
      inputProps={{...props, onChange: handleOnChange}}
      onSuggestionSelected={(e, {suggestion}) => {
        addTag(suggestion.name)
      }}
      onSuggestionsClearRequested={() => {}}
      onSuggestionsFetchRequested={() => {}}
    />
  )
}

A working example can be found in example/components/autocomplete.js.

How do I control the value of the input box?

Use inputValue and onChangeInput:

class Example extends React.Component {
  constructor() {
    super()
    this.state = {tags: [], tag: ''}
  }

  handleChange(tags) {
    this.setState({tags})
  }

  handleChangeInput(tag) {
    this.setState({tag})
  }

  render() {
    return (
      <TagsInput
        value={this.state.tags}
        onChange={::this.handleChange}
        inputValue={this.state.tag}
        onChangeInput={::this.handleChangeInput}
      />
    )
  }
}
How do I fix warning "unknown prop addTag"?

For ease of integration with auto complete components react-tagsinput passes the addTag method to renderInput props, if you are writing your own renderInput you need to filter addTag to not get an error about unknown prop addTag from React. Here is how it's done in the default renderInput function.

function defaultRenderInput ({addTag, ...props}) {
  let {onChange, value, ...other} = props
  return (
    <input type='text' onChange={onChange} value={value} {...other} />
  )
}
How do I copy paste from Excel?

All you need is to add a CR, carriage return, symbol (it is the default line break style in MS Office documents).

See answer on Stack Overflow.

Set the pasteSplit prop to this function:

pasteSplit(data) {
  const separators = [',', ';', '\\(', '\\)', '\\*', '/', ':', '\\?', '\n', '\r'];
  return data.split(new RegExp(separators.join('|'))).map(d => d.trim());
}

Component Interface

Props

value (required)

An array of tags.

onChange (required)

Callback when tags change, gets three arguments tags which is the new tag array, changed which is an array of the tags that have changed and changedIndexes which is an array of the indexes that have changed.

onChangeInput

Callback from the input box, gets one argument value which is the content of the input box. (onChangeInput is only called if the input box is controlled, for this to happen both inputValue and onChangeInput need to be set)

addKeys

An array of key codes that add a tag, default is [9, 13] (Tab and Enter).

currentValue

A string to set a value on the input.

inputValue

Similar to currentValue but needed for controlling the input box. (inputValue is only useful if you use it together with onChangeInput)

onlyUnique

Allow only unique tags, default is false.

validate

Allow only tags that pass this validation function. Gets one argument tag which is the tag to validate. Default is () => true.

validationRegex

Allow only tags that pass this regex to be added. Default is /.*/.

onValidationReject

Callback when tags are rejected through validationRegex, passing array of tags as the argument.

disabled

Passes the disabled prop to renderInput and renderTag, by default this will "disable" the component.

      {getTagDisplayValue(tag)}

function defaultRenderInput (props) {
  let {onChange, value, addTag, ...other} = props
