... 'import' => array( ... 'ext.select2.Select2', ... ), ...

##Advanced
... echo Select2::multiSelect("test", '', array('Apple','Banana','Orange','Apricot','Black Current'), array( 'required' => 'required', 'select2Options' => array( 'placeholder' => 'Please select a fruit', 'maximumSelectionSize' => 4, ), ) ); ... echo Select2::activeMultiSelect($model, "attr", array('test1','test2'), array( 'placeholder' => 'This is a placeholder', )); ...
Or this
... $this->widget('Select2', array( 'name' => 'exampleInput', 'value' => 1, 'data' => array( 1 => 'Apple', 2 => 'Banana', 3 => 'Orange', 4 => 'Apricot', ), )); ...
##Initialize options with javascript function or expressions Example populating text field with ajax support
... echo Select2::dropDownList('location', '', array(), array( 'empty'=>'', 'id'=>'location', 'style'=>'width:100%', 'select2Options'=>array( 'allowClear'=>true, 'placeholder'=>'Type Location Here', 'minimumInputLength'=>'3', 'ajax'=>array( 'url'=>'/homes/locationsajax/', 'type'=>'GET', 'dataType'=>'jsonp', 'data'=>new CJavaScriptExpression('function (term, page) {return {loc_name: term, page:page}}'), 'results'=>new CJavaScriptExpression('function (data, page) {return {results: data.locations}}'), ), 'initSelection'=>new CJavaScriptExpression('function(element, callback) { ' . 'var id=jQuery(element).val(); ' . 'if (id!=="") {' . ' jQuery.ajax("/homes/locationsajax/loc_id/"+id, { dataType: "jsonp" } ).done( function(data) {' . 'callback(data);' . '});' . '}}'), 'formatResult'=> new CJavaScriptExpression('locationFormatResult'), 'formatSelection'=>new CJavaScriptExpression('locationFormatSelection'), 'escapeMarkup'=>new CJavaScriptExpression('function (m) {return m;}'), ) ) ); ...
following javascript is rendered by extension with the above piece of php code
... $('#location').select2( { 'allowClear':true, 'placeholder':'Type Location Here', 'minimumInputLength':'3', 'ajax':{ 'url':'/homes/locationsajax/', 'type':'GET', 'dataType':'jsonp', 'data':function (term, page) {return {loc_name: term, page:page}}, 'results':function (data, page) {return {results: data.locations}}}, 'initSelection':function(element, callback) { var id=jQuery(element).val(); if (id!=="") { jQuery.ajax("/homes/locationsajax/loc_id/"+id, { dataType: "jsonp" } ) .done( function(data) { callback(data) } ); } }, 'formatResult':locationFormatResult, 'formatSelection':locationFormatSelection, 'escapeMarkup':function (m) {return m;} } ); ...
##Binding Events Examples with dropdown list A dropdown example triggering the events "select2-selecting" and "select2-removed" which fire on selecting a choice and clearing a choice
... echo Select2::dropDownList('area_type', '', array('sqft'=>'Square Feet','marla'=>'Marlas'), array('empty'=>'','id'=>'area_type','style'=>'width:100%', 'select2Options'=>array( 'allowClear'=>true, 'placeholder'=>'Unit Type', 'onTrigger'=>array( 'select2-selecting'=>new CJavaScriptExpression('function(e) { console.log(e.object.id);}'), "select2-removed"=>new CJavaScriptExpression('function(e) { console.log(e.choice.text);}'), ) ), ) ); ...
The following javascript is rendered when you run the above piece of code
... $('#area_type').select2( { 'allowClear':true, 'placeholder':'Unit Type' } ) .on('select2-selecting',function(e) { console.log(e.object.id);}) .on('select2-removed',function(e) { console.log(e.choice.text);}); ...
