@mention people in a textarea

#React Mentions

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

Getting started

1. Install the react-mentions package via NPM:

npm install react-mentions

2. Require the react-mentions package, which exports the two relevant React components for rendering the mentions textarea:

var mentions = require("react-mentions");

var MentionsInput = ReactMentions.MentionsInput;
var Mention = ReactMentions.Mention;

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

The MentionsInput supports the following props for configuring the widget:

Prop name	Type	Default value	Description

singleLine	boolean	false	Renders a single line text input instead of a textarea, if set to true
displayTransform	function (id, display, type)	returns display	Accepts a function for customizing the string that is displayed for a mention (optional)

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
type	string	null	Identifier for the data source, when using multiple data sources (optional)
data	array or function	null	An array of the mentionable data entries, or a filtering function that returns an array based on a query parameter
