Selectize selects and text inputs for Yii models and forms

Bootstrap 5 styling, multiple values, remote JSON choices and lifecycle cleanup

Quick start

Section titled “Quick start”

Installation

Section titled “Installation”

Configure the consuming application’s plugins and asset aliases with the installation guide, then install the documented branch:

Terminal window
composer require --prefer-dist yii2-extensions/selectize:^0.2

The native asset manager installs the published frontend assets without Node.js or a JavaScript build. Keep an existing application manager when it already supplies those assets.

Basic usage

Section titled “Basic usage”

Place this in a Yii view and associate the input with a visible label:

use yii\helpers\Html;
use yii2\extensions\selectize\Selectize;


echo Html::label('Category', 'category');
echo Selectize::widget(
    [
        'name' => 'category',
        'value' => 'yii',
        'items' => ['php' => 'PHP', 'yii' => 'Yii'],
        'options' => ['id' => 'category', 'prompt' => 'Choose a category'],
        'clientOptions' => ['maxItems' => 1],
    ],
);

Item keys are submitted values. To bind a model attribute in an ActiveForm:

use yii2\extensions\selectize\Selectize;


echo $form->field($model, 'tags')
    ->widget(
        Selectize::class,
        [
            'items' => ['php' => 'PHP', 'yii' => 'Yii'],
            'options' => ['multiple' => true],
            'clientOptions' => ['plugins' => ['remove_button']],
        ],
    );

The model must validate tags as an array; browser options do not authorize submitted values. See model validation for cleared fields and rejected submissions.
