Select2 Widget for Yii2

Select2 gives you a customizable select box with support for searching, tagging, remote data sets, infinite scrolling, and many other highly used options.

Install

Via Composer

$ composer require 2amigos/yii2-select2-widget

Usage

The Widget comes in two flavors, one for the classic and the bootstrap. The widgets, apart from the bootstrap one that requires some tweaks, are mostly configured throughout the clientOptions and clientEvents. Attributes that hold the configuration of the plugin and its events respectively.

For that reason, we highly recommend you to visit the Select2 Documentation for the possible options available on Select2 and Select2 Bootstrap Theme to check all the possible display options regarding Select2 with this theme.

Note We are in the process to create a website that will demo all our widgets, including this. The following are some basic samples to get you started. On the website, demos will be extensive and showing all possible configuration options.

Using Select2Widget

use dosamigos\select2\Select2:


// with \yii\bootstrap\ActiveForm;
echo $form
    ->field($model, 'attribute')
    ->widget(
        Select2::class, 
        [
            'items' => $data, // $data should be the same as the items provided to a regular yii2 dropdownlist
            'clientOptions' => ['theme' => 'classic']
        ]
    );
    
// as widget 
echo Select2::widget([
    'name' => 'my-name',
    'value' => 'my-value',
    'clientOptions' => [
        'maximumInputLength' => 20
    ]
]);

        [
            'items' => $data, // $data should be the same as the items provided to a regular yii2 dropdownlist
            'template' => '<div class="input-group">' .
