Yii2 Selectize Widget

Widget based on selectize.js extension https://selectize.github.io/selectize.js/

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist yii2mod/yii2-selectize "*"

or add

"yii2mod/yii2-selectize": "*"

to the require section of your composer.json.

Usage

Once the extension is installed, simply add widget to your page as follows:

1. Tagging input:

echo $form->field($model, "attribute")->widget(Selectize::className(), [
        'pluginOptions' => [
            'persist' => false,
            'createOnBlur' => true,
            'create' => true
        ]
]); 

2. Select input:

echo $form->field($model, "attribute")->widget(Selectize::className(), [
        'items' => [
            'Yes',
            'No'
        ],
        'pluginOptions' => [
            'persist' => false,
            'createOnBlur' => true,
            'create' => true
        ]
]); 

3. Tagging input with remote source and default values(If you want render select input, just setup items property):

Setup view file:

// setup the following to get the existing data from database
$model->attribute = 'first, last';
 
// or if the data is an array you can preselect the tags like this
$model->attribute = implode(', ', ["first", "last"]);

echo $form->field($model, "attribute")->widget(Selectize::className(), [
         'url' => '/site/search',
         'pluginOptions' => [
            'valueField' => 'name',
            'labelField' => 'name',
            'searchField' => ['name'],
            'persist' => false,
            'createOnBlur' => true,
            'create' => true
        ]
]);

Your action must return data in the json format, for example:

  public function actionSearch($query = null)
  {
      Yii::$app->response->format = Response::FORMAT_JSON;
      return [
          ['name' => 'Search Item 1'],
          ['name' => 'Search Item 2'],
      ];
  }

4. Usage widget with plugins:

echo Selectize::widget([
        'name' => 'tag-selectize',
        'options' => [
             'data-data' => $values ? Json::encode($values) : null // Set default values
        ],
        'pluginOptions' => [
             // define list of plugins 
            'plugins' => ['drag_drop', 'remove_button'],
            'persist' => false,
            'createOnBlur' => true,
            'create' => true
        ]
 ]);
