    ],
        
]);

Widget options ¶

Events:

• EVENT_BEFORE_REGISTER_DEFAULT_ASSET
• EVENT_AFTER_REGISTER_DEFAULT_ASSET

Usage in widget: ` echo SwiperSlider::widget([

...

'on ' . SwiperSlider::EVENT_AFTER_REGISTER_DEFAULT_ASSET => function(){

    CustomAsset::register($view);

}, ` showScrollbar: true | false. Default is false

showPagination: true | false. Default is true

slides: string | array | . Contents slides content like or any string. Or array with keys: value, options. value maybe like string or Closure (function($tag, $index, $self){}). Example: ` 'slides' => [

    [
        'value' => 'ggg',
        'options' => [
            'style' => ["background-image" => "url(https://swiperjs.com/demos/images/nature-1.jpg)"]
        ]
    ],
    [
        'value' => function($tag, $index, $self){
            return "some value {$index}";
        },
        'options' => [
            'style' => ["color" => "green"]
        ]
    ],

... __clientOptions__: array. This options is pasted when initialize Swiper js (new Swiper('options here')). Please, remember that if you are required to add javascript to the configuration of the js plugin and is required to be plain JS, make use of `JsExpression`. That class was made by Yii for that specific purpose. For example: 'clientOptions' => [

'slidesPerView' => 4,
'spaceBetween'=> 30,
'centeredSlides'=> true,
'pagination' => [
    'clickable' => true,
    'renderBullet' => new \yii\web\JsExpression("function (index, className) {
            return '<span class=\"' + className + '\">' + (index + 1) + '</span>';
        },
    "),
    ],
    "scrollbar" => [
        "el" => SwiperSlider::getItemCssClass(SwiperSlider::SCROLLBAR),
        "hide" => true,
    ],

], __options__: array. This options is pasted when rendered dom elements. Various attributes for html elements are set here. This params allowed only for all template items: //Global styles to elements. If create styles for all slides 'options' => [

'styles' => [
    SwiperSlider::CONTAINER => ["height" => "100px"],
    SwiperSlider::SLIDE => ["text-align" => "center"],
],
'class' => [SwiperSlider::CONTAINER => ["myClass"],]

],

It is best to use constants to specify template elements:
* CONTAINER = 'container';
* WRAPPER = 'wrapper';
* SLIDE = 'slide';
* PAGINATION = 'pagination';
* BUTTON_PREV = 'button-prev';
* BUTTON_NEXT = 'button-next';
* SCROLLBAR = 'scrollbar';

## Testing

Run tests in extention folder.

```bash
$ ./vendor/bin/phpunit

Note! For running all tests needed upload all dependencies by composer. If tested single extention, then run command from root directory where located extention: composer update

When all dependencies downloaded run all tests in terminal from root folder: ./vendor/bin/phpunit tests Or for only unit: ./vendor/bin/phpunit --testsuite Unit

If extention tested in app, then set correct path to phpunit and run some commands.
