Dual Listboxt for Yii framework 2.0.

Description

softark\duallistbox\DualListbox widget is a Yii 2 wrapper for Bootstrap Dual Listbox.

It works with bootstrap 3, 4, or 5

Requirements

• Yii Version 2.0.0 or later
• yii2-bootstrap, yii2-bootstrap4 or yii2-bootstrap5
• istvan-ujjmeszaros/bootstrap-duallistbox v.3.0.x or v.4.0.x

Usage

1. Add softark/yii2-dual-listbox and istvan-ujjmeszaros/bootstrap-duallistbox in your project's composer.json, and let Composer configure your project.

   • You have to use a different version of istvan-ujjmeszaros/bootstrap-duallistbox depending on the bootstrap version.
   • For bootstrap 3, use ~3.0.0 :

   "require": {  "php": ">=7.0.0", "yiisoft/yii2": "*",  "yiisoft/yii2-bootstrap": "*",  "istvan-ujjmeszaros/bootstrap-duallistbox": "~3.0.0", "softark/yii2-dual-listbox": "dev-master" },

   • For bootstrap 4 and 5, use ~4.0.0:

   "require": {  "php": ">=7.0.0", "yiisoft/yii2": "*",  "yiisoft/yii2-bootstrap4": "*", // OR  "yiisoft/yii2-bootstrap5": "*",  "istvan-ujjmeszaros/bootstrap-duallistbox": "~4.0.0", "softark/yii2-dual-listbox": "dev-master" },

2. Use softark\duallistbox\DualListbox::widget() in place of yii\helpers\Html::listBox(), yii\helpers\Html::activeListBox(), or yii\widgets\ActiveField::listBox() in your view.

   1. Replacing Html::listBox() using name and selection

      use softark\duallistbox\DualListbox; ... <?php $options = [ 'multiple' => true, 'size' => 20, ]; // echo Html::listBox($name, $selection, $items, $options); echo DualListbox::widget([ 'name' => $name, 'selection' => $selection, 'items' => $items, 'options' => $options, 'clientOptions' => [ 'moveOnSelect' => false, 'selectedListLabel' => 'Selected Items', 'nonSelectedListLabel' => 'Available Items', ], ]); ?>

   2. Replacing Html::activeListBox() using model and attribute

      use softark\duallistbox\DualListbox; ... <?php $options = [ 'multiple' => true, 'size' => 20, ]; // echo Html::activeListBox($model, $attribute, $items, $options); echo DualListbox::widget([ 'model' => $model, 'attribute' => $attribute, 'items' => $items, 'options' => $options, 'clientOptions' => [ 'moveOnSelect' => false, 'selectedListLabel' => 'Selected Items', 'nonSelectedListLabel' => 'Available Items', ], ]); ?>

   3. Replacing ActiveField::listBox() using model and attribute

      use softark\duallistbox\DualListbox; ... <?php $options = [ 'multiple' => true, 'size' => 20, ]; // echo $form->field($model, $attribute)->listBox($items, $options); echo $form->field($model, $attribute)->widget(DualListbox::className(),[ 'items' => $items, 'options' => $options, 'clientOptions' => [ 'moveOnSelect' => false, 'selectedListLabel' => 'Selected Items', 'nonSelectedListLabel' => 'Available Items', ], ]); ?>

3. Collect the user input in the server side, just as you do with a single Listbox with multiple selection. Note that the input value will be an array.

   If you find difficulty in handling the user input, please read A Sample Code which demonstrates how to use a dual listbox to the data in array format.

Properties of softark\duallistbox\DualListbox

1. name @var string

   The input name.

2. selection @var array

   The selected values.

3. model @var yii\base\Model

   The model object.

4. attribute @var string

   The attribute name.

5. items @var array

   The option data items. The array keys are option values, and the array values are the corresponding option labels.

6. options @var array

   The tag options for the listbox in terms of name-value pairs.

7. clientOptions @var array

   The options for the Bootstrap Dual Listbox in terms of name-value pairs. See Initialzation parameters object section of the official documentation of Bootstrap Dual Listbox for details.

The first 6 properties correspond to the parameters used in Html::listBox(), Html::activeListBox() and ActiveField::listBox().

Note that you have to use either name-selection pair or model-attribute pair. The former is for replacing Html::listBox() and the latter is for Html::activeListBox() and ActiveField::listBox().

Notice

For some reason, Bootstrap Dual Listbox doesn't work in mobile device browsers, and so you can not use this widget for them.

Consider using checkbox list instead.
