React Mentions

A React component that let's you mention people in a textarea like you are used to on Facebook or Twitter.

Used in production at Signavio, State, Snips, Swat.io, GotDone, Volinspire, Marvin, Timely, GuideFitter, Evite, Publer, Kontentino, and you?

Getting started

Install the react-mentions package via npm:

npm install react-mentions --save

Or yarn:

yarn add react-mentions

The package exports two React components for rendering the mentions textarea:

import { MentionsInput, Mention } from 'react-mentions'

MentionsInput is the main component rendering the textarea control. It takes one or multiple Mention components as its children. Each Mention component represents a data source for a specific class of mentionable objects, such as users, template variables, issues, etc.

Example:

You can find more examples here: demo/src/examples

Configuration

The MentionsInput supports the following props for configuring the widget:

Each data source is configured using a Mention component, which has the following props:

If a function is passed as the data prop, that function will be called with the current search query as first, and a callback function as second argument. The callback can be used to provide results asynchronously, e.g., after fetch requests. (It can even be called multiple times to update the list of suggestions.)

Styling

react-mentions supports css, css modules, and inline styles. It is shipped with only some essential inline style definitions and without any css. Some example inline styles demonstrating how to customize the appearance of the MentionsInput can be found at demo/src/examples/defaultStyle.js.

If you want to use css, simply assign a className prop to MentionsInput. All DOM nodes rendered by the component will then receive class name attributes that are derived from the base class name you provided.

If you want to avoid global class names and use css modules instead, you can provide the automatically generated class names as classNames to the MentionsInput. See demo/src/examples/CssModules.js for an example of using react-mentions with css modules.

You can also assign className and style props to the Mention elements to define how to highlight the mentioned words.

Testing

Due to react-mentions' internal cursor tracking it is not good enough to simulate the editing of the textarea value using ReactTestUtils.Simulate.change. We recommend using @testing-library/user-event for a realistic simulation of events as they would happen in the browser as the user interacts the textarea.
