$data = [
    "red" => "red",
    "green" => "green",
    "blue" => "blue",
    "orange" => "orange",
    "white" => "white",

    "teal" => "teal"
];

// Tagging support Multiple
$model->colorTags =  ['red', 'green']; // initial value
echo $form->field($model, 'colorTags')->widget(Select2::classname(), [
    'data' => $data,
    'options' => ['placeholder' => 'Select a color ...', 'multiple' => true],
    'pluginOptions' => [
        'tags' => true,
        'tokenSeparators' => [',', ' '],
        'maximumInputLength' => 10
