        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" => \algsupport\yii2-swiperjs-8\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' => [
        \algsupport\yii2-swiperjs-8\SwiperSlider::CONTAINER => ["height" => "100px"],
        \algsupport\yii2-swiperjs-8\SwiperSlider::SLIDE => ["text-align" => "center"],
    ],
    'class' => [\algsupport\yii2-swiperjs-8\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';
