Create tags in React

Tags are the keywords associated to a piece of information. Tags are often used on social websites, email systems, blogs where users can upload their own content. They are separated by comma or enter. Here we will create tags in react applications with the help of react-tag-input component.

Installation

npm install --save react-tag-input

Now, we have <ReactTags /> component which we can use in our class or functional component. Here, we are using this in our App Component.

Create tags in React

import React, { useState } from 'react';
import { render } from 'react-dom';
import { WithContext as ReactTags } from 'react-tag-input';

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

const delimiters = [KeyCodes.comma, KeyCodes.enter];

const App = () => {

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

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

  const handleAddition = tag => {
    setTags([...tags, tag]);
  };

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

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

    setTags(newTags);
  };

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

  const suggestions = [
      {
        id: 'India',
        text: 'India'
      },
      {
        id: 'USA',
        text: 'USA'
      }
  ];

  return (
    <div className="app">
      <h1> React Tags Example </h1>
      <div>
        <ReactTags
          tags={tags}
          suggestions={suggestions}
          delimiters={delimiters}
          handleDelete={handleDelete}
          handleAddition={handleAddition}
          handleDrag={handleDrag}
          handleTagClick={handleTagClick}
          inputFieldPosition="bottom"
          autocomplete
        />
      </div>
    </div>
  );
};

render(<App />, document.getElementById('root'));
