react-typeahead

A typeahead/autocomplete component for React

react-typeahead is a javascript library that provides a react-based typeahead, or autocomplete text entry, as well as a "typeahead tokenizer", a typeahead that allows you to select multiple results.

Usage

For a typeahead input:

var Typeahead = require('react-typeahead').Typeahead;
React.render(
  <Typeahead
    options={['John', 'Paul', 'George', 'Ringo']}
    maxVisible= 2
  />
);

For a tokenizer typeahead input:

var Tokenizer = require('react-typeahead').Tokenizer;
React.render(
  <Tokenizer
    options={['John', 'Paul', 'George', 'Ringo']}
    onTokenAdd={function(token) {
      console.log('token added: ', token);
    }}
  />
);

Examples

• Basic Typeahead with Topcoat
• Typeahead Tokenizer with Topcoat
