If using Webpack make sure to include the style-loader in your webpack config:

module: {
    loaders: [
        { test: /\.css$/, loader: "style-loader!css-loader" },
        { test: /\.jsx?$/, loaders: ['react-hot', 'jsx-loader?harmony']}
    ]
}

Props

Prop	Description
placeholder	Placeholder text for input
limit	Number of results to show in dropdown
thumbStyle	Set result images to "circle" or "square"
loadingIcon	Path to custom loading icon
requestHandler	Required function that fetches data, adds "image" and "name" fields to all response objects, and then passes data back to instatype component. See an example requestHandler function below.
selectedHandler	Required function that is called when a dropdown result is clicked. This will be passed the full object initially used to populate that result in the dropdown.

Example requestHandler

Data fetching is done by a custom function that you pass in via the requestHandler prop. This way you can use your preferred ajax library and alter the response data client-side before passing it to instatype. After fetching data make sure to give each object a "name" and optional "image" value, and then pass the final data to callback() to populate the instatype component. Here's an example.

requestHandlerUsers: function(query, limit, callback){

  $.ajax({
    url: "https://api.instagram.com/v1/users/search",
    dataType: "jsonp",
    data: {
      client_id: this.props.instagramClientId,
      q: query,
      count: limit
    },
    success: function(data) {
      // Instatype expects an "image" and "name" for each result
      var renamedData = data.data.map(function(result){
        result.image = result.profile_picture;
        result.name = result.username;
        return result;
      });
      
      callback(renamedData);
    }
  });

}
