react-tags

Features

  • Autocomplete based on a suggestion list
  • Keyboard friendly and mouse support
  • Reorder tags using drag and drop

Why

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.

Installation

The preferred way of using the component is via NPM

npm install --save react-tag-input

It is, however, also available to be used separately (dist/ReactTags.min.js). If you prefer this method remember to include ReactDND as a dependancy. Refer to the example to see how this works.

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

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

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

class App extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            tags: [
                { id: "Thailand", text: "Thailand" },
                { id: "India", text: "India" }
             ],
            suggestions: [
                { id: 'USA', text: 'USA' },
                { id: 'Germany', text: 'Germany' },
                { id: 'Austria', text: 'Austria' },
                { id: 'Costa Rica', text: 'Costa Rica' },
                { id: 'Sri Lanka', text: 'Sri Lanka' },
                { id: 'Thailand', text: 'Thailand' }
             ]
        };
        this.handleDelete = this.handleDelete.bind(this);
        this.handleAddition = this.handleAddition.bind(this);
        this.handleDrag = this.handleDrag.bind(this);
    }

    handleDelete(i) {
        const { tags } = this.state;
        this.setState({
         tags: tags.filter((tag, index) => index !== i),
        });
    }

    handleAddition(tag) {
        this.setState(state => ({ tags: [...state.tags, tag] }));
    }

    handleDrag(tag, currPos, newPos) {
        const tags = [...this.state.tags];
        const newTags = tags.slice();

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

        // re-render
        this.setState({ tags: newTags });
    }

    render() {
        const { tags, suggestions } = this.state;
        return (
            <div>
                <ReactTags tags={tags}
                    suggestions={suggestions}
                    handleDelete={this.handleDelete}
                    handleAddition={this.handleAddition}
                    handleDrag={this.handleDrag}
                    delimiters={delimiters} />
            </div>
        )
    }
};

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