The placeholder can be declared via a data-placeholder attribute attached to the select, or via the placeholder configuration element as seen in the example code

Optionally, a clear button (visible once a selection is made) is available to reset the select box back to the placeholder value.

Loading Data

-             
Select2 uses a function to load result data. Here is a trivial example that creates choices that consist of user's input repeated a number of times:

-             

-                 
-             

-             
In order to take advantage of custom data loading Select2 should be attached to an input type='hidden' tag, otherwise data is parsed from select's option tags.

Loading Array Data

-            
Select2 provides some shortcuts that make it easy to access local data stored in an array instead of having to write a query function mentioned in the example above.

-            
Example below inlines the data by specifying an array in the data element. Items in such an array must have id and text keys.

-            

-                
-            

-            
If your data does not have a text key, an alternative key can be specified as a string:

-             

-                 
-             

-

Loading Remote Data

-              
Select2 comes with AJAX/JSONP support built in. In this example we will search for a movie using Rotten Tomatoes API:

-              

-                  
-              

-               
If this example does not work it is probably because the Rotten Tomatoes API key usage of 10000 requests per day has been exhausted. Please try again tomorrow.

-              
Example Code

-              

-              
Select2 uses jQuery's $.ajax function to execute the remote call by default. An alternative transport function can be specified in the ajax settings, or an entirely custom implementation can be built by providing a custom query function instead of using the ajax helper

Select2 supports lazy-appending of results when the result list is scrolled to the end.
+            In order to enable the remote service must support some sort of a paging mechanism and
+            the query function given to Select2 must take advantage of it. The following example demonstrates
+            how this can be set up. Search for some keyword and then scroll the result list to the end to
+            see more results load:

Reacting to external value changes

 
-              
Select2 can react to external value changes and keep its selection in-sync. This feature allows
-                  Select2 to work seamlessly with front-end frameworks that use data binding between ui components
-                  and model values.

-              


-              
 

-              
This feature is only available when initSelection() function is provided in
-                  the options. This function is needed to map the choice ids set on the element to objects used by
-                  Select2. This function is set by default when Select2 is attached to a select or when
-                  the tags helper function is used.

Select2 Drag and Drop Sorting

+        

+            Select2 supports drag and drop sorting of selected choices. Select2 does not, itself, provide the necessary code to perform dragging and dropping, instead it provides hooks that other libraries can use to provide the behavior. In this example we are using JQuery UI's sortable() plugin.
+        

+        
The sorting is only available when Select2 is attached to a hidden input field.

Custom Matcher

Unlike other dropdowns on this page, this one matches options only if the term appears in the beginning of the string as opposed to anywhere

-                    populated in order to keep the search field. This
-                    is useful for cases where local data is used with just a few results, in which case the search box

Initial value that is selected if no other selection is made.

-                

-                    The value can be specified either as an object or as a string. If
-                    specified as a string any custom formatSelection function will be
-                    bypassed and the string value will be rendered directly.
-                

-                
The placeholder can also be specified as a data-placeholder attribute on the select
-                    or input element that Select2 is attached to. In this case only string

-                    is selected in
-                    non-multi-value select boxes an empty first option element must be provided (<option></option>)

-                        when clicked, resets the value of the select box back to the placeholder, thus this option is

options.termstringSearch string entered by user
options.pageint1-based page number tracked by Select2 for use with infinite scrolling of results
options.contextobjectAn object that persists across the lifecycle of queries for the same search term (the query to retrieve the initial results, and subsequent queries to retrieve more result pages for the same search term). When this function is first called for a new search term this object will be null. The user may choose to set any object in the results.context field - this object will then be used as the context parameter for all calls to the query method that will load more search results for the initial search term. The object will be reset back to null when a new search term is queried. This feature is useful when a page number is not easily mapped against the server side paging mechanism. For example, some server side paging mechanism may return a "continuation token" that needs to be passed back to them in order to retrieve the next page of search results.

+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+
