React Mentions

REUSE status

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,, GotDone, Volinspire, Marvin, Timely, GuideFitter, Evite, Publer, Kontentino,, Highlight 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.


<MentionsInput value={this.state.value} onChange={this.handleChange}>

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


The MentionsInput supports the following props for configuring the widget:

Prop name Type Default value Description
value string '' The value containing markup for mentions
onChange function (event, newValue, newPlainTextValue, mentions) empty function A callback that is invoked when the user changes the value in the mentions input
onKeyDown function (event) empty function A callback that is invoked when the user presses a key in the mentions input
singleLine boolean false Renders a single line text input instead of a textarea, if set to true
onBlur function (event, clickedSuggestion) empty function Passes true as second argument if the blur was caused by a mousedown on a suggestion
allowSpaceInQuery boolean false Keep suggestions open even if the user separates keywords with spaces.
suggestionsPortalHost DOM Element undefined Render suggestions into the DOM in the supplied host element.
inputRef React ref undefined Accepts a React ref to forward to the underlying input element
allowSuggestionsAboveCursor boolean false Renders the SuggestionList above the cursor if there is not enough space below
forceSuggestionsAboveCursor boolean false Forces the SuggestionList to be rendered above the cursor
a11ySuggestionsListLabel string '' This label would be exposed to screen readers when suggestion popup appears
customSuggestionsContainer function(children) empty function Allows customizing the container of the suggestions

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

Prop name Type Default value Description
trigger regexp or string '@' Defines the char sequence upon which to trigger querying the data source
data array or function (search, callback) null An array of the mentionable data entries (objects with id & display keys, or a filtering function that returns an array based on a query parameter
renderSuggestion function (entry, search, highlightedDisplay, index, focused) null Allows customizing how mention suggestions are rendered (optional)
markup string '@[__display__](__id__)' A template string for the markup to use for mentions
displayTransform function (id, display) returns display Accepts a function for customizing the string that is displayed for a mention
regex RegExp automatically derived from markup pattern Allows providing a custom regular expression for parsing your markup and extracting the placeholder interpolations (optional)
onAdd function (id, display, startPos, endPos) empty function Callback invoked when a suggestion has been added (optional)
appendSpaceOnAdd boolean false Append a space when a suggestion has been added (optional)

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.)


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.


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.

If you want to contribute, first of all: thank you ❤️. Please check and/or create an issue.
