React tags

React-tags is a simple tagging component ready to drop in your projects. The component is inspired by GMail's To field in the compose window.

Features

• Autocomplete based on a suggestion list
• Keyboard friendly and mouse support
• Reorder tags using drag and drop
• Edit tag support
• Optional clear all button

Why

Started by Prakhar Srivastav and later maintained by Aakansha Doshi.

In Prakhar's words here is why he started it👇🏻

Because I was looking for an excuse to build a standalone component and publish it in the wild? To be honest, I needed a tagging component that provided the above features for my React-Surveyman project. Since I was unable to find one which met my requirements (and the fact that I generally enjoy re-inventing the wheel) this is what I came up with.

Demo

Installation

You can use npm

npm install --save react-tag-input

or via Yarn

yarn add react-tag-input

make sure you have installed the peer dependencies as well with 👇 versions

 "react": "^18.2.0",
 "react-dnd": "^14.0.2",
 "react-dnd-html5-backend": "^14.0.0",
 "react-dom": "^18.2.0"

Usage

Here's a sample implementation that initializes the component with a list of initial tags and suggestions list. Apart from this, there are multiple events, handlers for which need to be set. For more details, go through the API.

import React from 'react';
import { createRoot } from 'react-dom/client';
import { StrictMode } from 'react';
import GitHubCorner from './GithubCorner';
import type { Tag } from '../src/components/SingleTag';
import { WithContext as ReactTags, SEPARATORS } from '../src/index';
;

const suggestions = COUNTRIES.map((country) => {
  return {
    id: country,
    text: country,
    className: '',
  };
});

const KeyCodes = {
  comma: 188,
  enter: [10, 13],
};


const App = () => {
  const [tags, setTags] = React.useState>([
    { id: 'Thailand', text: 'Thailand', className: '' },
    { id: 'India', text: 'India', className: '' },
    { id: 'Vietnam', text: 'Vietnam', className: '' },
    { id: 'Turkey', text: 'Turkey', className: '' },
  ]);

  const handleDelete = (index: number) => {
    setTags(tags.filter((_, i) => i !== index));
  };

  const onTagUpdate = (index: number, newTag: Tag) => {
    const updatedTags = [...tags];
    updatedTags.splice(index, 1, newTag);
    setTags(updatedTags);
  };

  const handleAddition = (tag: Tag) => {
    setTags((prevTags) => {
      return [...prevTags, tag];
    });
  };

  const handleDrag = (tag: Tag, currPos: number, newPos: number) => {
    const newTags = tags.slice();

    newTags.splice(currPos, 1);
    newTags.splice(newPos, 0, tag);

    // re-render
    setTags(newTags);
  };

  const handleTagClick = (index: number) => {
    console.log('The tag at index ' + index + ' was clicked');
  };

  const onClearAll = () => {
    setTags([]);
  };

  return (
    <div>
      

      <h1> React Tags Example </h1>
      <div>
        
      </div>
    </div>
  );
};
const domNode = document.getElementById('app')!;
const root = createRoot(domNode);

root.render(
  
    
  
);

A note about Contexts One of the dependencies of this component is the react-dnd library. Since the 1.0 version, the original author has changed the API and requires the application using any draggable components to have a top-level backend context. So if you're using this component in an existing Application that uses React-DND you will already have a backend defined, in which case, you should require the component without the context.

const ReactTags = require('react-tag-input').WithOutContext;

Otherwise, you can simply import along with the backend itself (as shown above). If you have ideas to make this API better, I'd love to hear.

Options

Styling

`` does not come up with any styles. However, it is very easy to customize the look of the component the way you want it. By default, the component provides the following classes with which you can style -

• ReactTags__tags
• ReactTags__tagInput
• ReactTags__tagInputField
• ReactTags__selected
• ReactTags__selected ReactTags__tag
• ReactTags__selected ReactTags__remove
• ReactTags__suggestions
• ReactTags__activeSuggestion
• ReactTags__editTagInput
• ReactTags__editTagInputField
• ReactTags__clearAll

An example can be found in /example/reactTags.css.

If you need to set your own class names on the component, you may pass in a classNames prop.

Preparing for Migration to v7.x.x

Below are the list of deprecated props so please stop using it and migrate to the new props as these will be removed in v7.x.x. You will see a warning for the migration as well in the console.

• delimiters - Please use separators instead, more info in this issue.
• inline - Please use inputFieldPosition instead.
• autofocus - Please use autoFocus instead.

Additionally the prop autocomplete is deprecated and will be removed in v7.x.x. If you have any concerns regarding this, please share your thoughts in this issue.

Got ideas on how to make this better? Open an issue!

Thanks

The autocomplete dropdown is inspired by Lea Verou's awesomeplete library. The Drag and drop functionality is provided by Dan Abramov's insanely useful ReactDND library.

Also thanks to the awesome contributors who've made the library far better!

tags

An array of tags that are displayed as pre-selected. Each tag should have an id property, property for the label, which is specified by the labelField and class for label, which is specified by className.

// With default labelField
const tags =  [ { id: "1", text: "Apples" } ]

// With labelField of `name`
const tags =  [ { id: "1", name: "Apples" } ]

// With className
const tags = [ { id: "1", text: "Apples", className: 'red'} ]

suggestions

An array of suggestions that are used as basis for showing suggestions. These objects should follow the same structure as the tags. So if the labelField is name, the following would work:

// With labelField of `name`
const suggestions = [
    { id: "1", name: "mango" },
    { id: "2", name: "pineapple"},
    { id: "3", name: "orange" },
    { id: "4", name: "pear" }
];

delimiters

This prop is deprecated and will be removed in 7.x.x. Please use separators instead. Specifies which characters should terminate tags input. An array of character codes. We export the constant KEYS for convenience.

import { WithContext as ReactTags, KEYS } from 'react-tag-input';

separators

Specifies which characters should separate tags. An array of strings. We support the below separators 👇

• Enter
• Tab
• Space
• Comma
• Semicolon

And we export the constant SEPERATORS for convenience.

import { WithContext as ReactTags, SEPARATORS } from 'react-tag-input';

placeholder

The placeholder shown for the input.

let placeholder = "Add new country"

labelField

Provide an alternative label property for the tags.

This is useful if your data uses the text property for something else.

handleAddition

Function called when the user wants to add a tag (either a click, a tab press or carriage return)

function(tag) {
    // add the tag to the tag list
}

handleDelete

Function called when the user wants to delete a tag

function(i) {
    // delete the tag at index i
}

handleDrag

If you want tags to be draggable, you need to provide this function. Function called when the user drags a tag.

function(tag, currPos, newPos) {
    // remove tag from currPos and add in newPos
}

handleFilterSuggestions

To assert control over the suggestions filter, you may contribute a function that is executed whenever a filtered set of suggestions is expected. By default, the text input value will be matched against each suggestion, and those that start with the entered text will be included in the filters suggestions list. If you do contribute a custom filter function, you must return an array of suggestions. Please do not mutate the passed suggestions array.

For example, if you prefer to override the default filter behavior and instead match any suggestions that contain the entered text anywhere in the suggestion, your handleFilterSuggestions property may look like this:

function(textInputValue, possibleSuggestionsArray) {
    var lowerCaseQuery = textInputValue.toLowerCase()

    return possibleSuggestionsArray.filter(function(suggestion)  {
        return suggestion.toLowerCase().includes(lowerCaseQuery)
    })
}

Note: The above custom filter uses String.prototype.includes, which was added to JavaScript as part of the ECMAScript 7 specification. If you need to support a browser that does not yet include support for this method, you will need to either refactor the above filter based on the capabilities of your supported browsers, or import a polyfill for String.prototype.includes.

handleTagClick

Function called when the user wants to know which tag was clicked

function(i) {
    // use the tag details at index i
}

autofocus

Optional boolean param to control whether the text-input should be autofocused on mount. This prop is deprecated and will be removed in 7.x.x, please use autoFocus instead.

autoFocus

Optional boolean param to control whether the text-input should be autofocused on mount.

allowDeleteFromEmptyInput

Optional boolean param to control whether tags should be deleted when the Backspace key is pressed in an empty Input Box. By default this prop is false.

However when input field position is inline, you will be able to delete the tags by pressing Backspace irrespective of the value of this prop.

This prop will likely be removed in future versions.

handleInputChange

Optional event handler for input onChange

Signature

(value, event) => void

The value denotes the target input value to be added and the event is the original event for onChange.

handleInputFocus

Optional event handler for input onFocus

Signature

(value, event) => void

The value denotes the target input value to be added and the event is the original event for onFocus.

handleInputBlur

Optional event handler for input onBlur

Signature

(value, event) => void

The value denotes the target input value to be added and the event is the original event for onBlur.

minQueryLength

Minimum number of characters needed for suggestions to appear. Defaults to 2.

removeComponent

If you'd like to supply your own tag delete/remove element, create a React component and pass it as a property to ReactTags using the removeComponent option. By default, a simple anchor link with an "x" text node as its only child is rendered, but if you'd like to, say, replace this with a <button> element that uses an image instead of text, your markup may look something like this:

import {WithContext as ReactTags} from 'react-tag-input'

class Foo extends React.Component {
   render() {
      return 
   }
}

class RemoveComponent extends React.Component {
   render() {
     const { className, onRemove } = this.props;
      return (
         </button><button>
            <img src="my-icon.png">
         </button>
      )
   }
}

The below props will be passed to the removeComponent. You will need to forward the relevant props to your custom remove component to make it work.

{ id?: string, className: string, key: string }

autocomplete

This prop is deprecated and will be removed in 7.x.x to simplify the integration and make it more intutive. If you have any concerns regarding this, please share your thoughts in https://github.com/react-tags/react-tags/issues/949.

Useful for enhancing data entry workflows for your users by ensuring the first matching suggestion is automatically converted to a tag when a separator key is pressed (such as the enter key). This option has three possible values:

• true - when separator key (such as enter) is pressed, first matching suggestion is used.
• 1 - when separator key (such as enter) is pressed, matching suggestion is used only if there is a single matching suggestion
• false (default) - tags are not autocompleted on enter/separator key press.

This option has no effect if there are no suggestions.

readOnly

Renders the component in read-only mode without the input box and removeComponent. This also disables the drag-n-drop feature.

name

The name attribute added to the input.

id

The id attribute added to the input.

maxLength

The maxLength attribute added to the input. Specifies the maximum number of characters allowed in the input field.

inline

The inline attributes decides whether the input fields and selected tags will be rendered in-line.

This attribute is deprecated and will be removed in v7.x.x, see inputFieldPosition.

inputFieldPosition

The inputFieldPosition attribute decides the positioning of the input field relative to the tags. Can be one of inline, top or bottom.

allowUnique

This prop controls whether tags should be unique.

allowDragDrop

This prop controls whether tags should have the drag-n-drop feature enabled.

renderSuggestion

This props allows to provide your own suggestion renderer and override the default one. It receives the suggestion and the query string as parameters. For example:

 <div style="{{">{text} ({ query })</div>}
    ...&gt;

inputProps

When you want to pass additional attributes to the input element (for example autocomplete, disabled etc) you can use this prop.

allowAdditionFromPaste

This prop implies whether to allow paste action for adding tags. Defaults to true.

editable

This prop implies whether the tags should be editable. Defaults to false.

onTagUpdate

onTagUpdate(editIndex, tag) => void;

This callback is if present is triggered when tag is updated. The edit index and the tag are passed in the callback. You can update the tags prop in this callback.

clearAll

This props implies whether 'clear all' button should be shown. Defaults to false.

onClearAll

This callback is if present is triggered when "clear all" button is clicked. You can set the tags prop to empty in this callback.

maxTags

This prop specifies the maximum count of tags to be added. Incase the tags exceed, error will show up to convey the maximum tag limit has reached.
