JarCastingAngular Chosen Localytics 
AngularJS Chosen directive
This directive brings the Chosen jQuery plugin into AngularJS with ngModel and ngOptions integration.
To use, include localytics.directives as a dependency in your Angular module. You can now use the chosen directive as an attribute on any select element. Angular version 1.3+ is required, but recommended 1.4.9+.

Features
- Works with
ngModelandngOptions - Supports usage of promises in
ngOptions - Provides a 'loading' animation when 'ngOptions' collection is a promise backed by a remote source
- Pass options to
Chosenvia attributes or by passing an object to the Chosen directive - Provider with default values with
chosenProvider(read: Added config-provider) [since 1.6.0]
Usage
Simple example
Similar to $("#states").chosen()
<select chosen multiple id="states">
<option value="AK">Alaska</option>
<option value="AZ">Arizona</option>
<option value="AR">Arkansas</option>
<option value="CA">California</option>
</select>
Pass any chosen options as attributes
<select chosen
data-placeholder-text-single="'Pick one of these'"
disable-search="true"
allow-single-deselect="true">
<option value=""></option>
<option>This is fun</option>
<option>I like Chosen so much</option>
<option>I also like bunny rabbits</option>
</select>
Note: the empty option element is mandatory when using
allow-single-deselect
Integration with ngModel and ngOptions
<select multiple
chosen
ng-model="state"
ng-options="s for s in states">
</select>
Note: don't try to use
ngModelwithngRepeat. It won't work. UsengOptions. It's better that way.
Also important: if your
ngModelis null or undefined, you must manually include an empty option inside your<select>, otherwise you'll encounter strange off-by-one errors:
<select multiple
chosen
ng-model="state"
ng-options="s for s in states">
<option value=""></option>
</select>
This annoying behavior is alluded to in the examples in the documentation for ngOptions.
Works well with other AngularJS directives
<select chosen
ng-model="state"
ng-options="s for s in states"
ng-disabled="editable">
<option value=""></option>
</select>
Loading from a remote data source
Include chosen-spinner.css and spinner.gif to show an Ajax spinner icon while your data is loading. If the collection comes back empty, the directive will disable the element and show a default "No values available" message. You can customize this message by passing in noResultsText in your options.
app.js
angular.module('App', ['ngResource', 'localytics.directives'])
.controller('BeerCtrl', function($scope, $resource) {
$scope.beers = $resource('api/beers').query()
});
index.html
<div ng-controller="BeerCtrl">
<select chosen
data-placeholder-text-single="'Choose a beer'"
no-results-text="'Could not find any beers :('"
ng-model="beer"
ng-options="b for b in beers">
<option value=""></option>
</select>
</div>

Note: Assigning promises directly to scope is now deprecated in Angular 1.2+. Assign the results of the promise to scope once the promise returns. The loader animation will still work as long as the collection expression evaluates to
undefinedwhile your data is loading!
Default values with chosenProvider (thanks @zlodes) [since 1.6.0]
angular.module('chosenExampleApp', ['localytics.directives'])
.config(['chosenProvider', function (chosenProvider) {
chosenProvider.setOption({
no_results_text: 'There is no results!',
placeholder_text_multiple: 'Choose one or more!'
});
}]);
