+* **objects**:  
+  When `source` defined as array of objects, e.g. `[{value: 1, text: "text1"}, {value: 2, text: "text2"}, ...]`.

+Select2
+=================
+
+Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results. Look and feel of Select2 is based on the excellent [Chosen](http://harvesthq.github.com/chosen/) library.
+
+To get started -- checkout http://ivaynberg.github.com/select2!
+
+What Does Select2 Support That Chosen Does Not?
+-------------------------------------------------
+
+* Working with large datasets: Chosen requires the entire dataset to be loaded as `option` tags in the DOM, which limits
+it to working with small-ish datasets. Select2 uses a function to find results on-the-fly, which allows it to partially
+load results.
+* Paging of results: Since Select2 works with large datasets and only loads a small amount of matching results at a time
+it has to support paging. Select2 will call the search function when the user scrolls to the bottom of currently loaded
+result set allowing for the 'infinite scrolling' of results.
+* Custom markup for results: Chosen only supports rendering text results because that is the only markup supported by
+`option` tags. Select2 provides an extension point which can be used to produce any kind of markup to represent results.
+* Ability to add results on the fly: Select2 provides the ability to add results from the search term entered by the user, which allows it to be used for
+tagging.
+
+Browser Compatibility
+--------------------
+* IE 8+ (7 mostly works except for [issue with z-index](https://github.com/ivaynberg/select2/issues/37))
+* Chrome 8+
+* Firefox 3.5+
+* Safari 3+
+* Opera 10.6+
+
+Integrations
+------------
+
+* [Wicket-Select2](https://github.com/ivaynberg/wicket-select2) (Java / Apache Wicket)
+* [select2-rails](https://github.com/argerim/select2-rails) (Ruby on Rails)
+* [AngularUI](http://angular-ui.github.com/#directives-select2) ([AngularJS](angularjs.org))
+* [Django](https://github.com/applegrew/django-select2)
