The gallery uses standard markup for cards and image nodes. In the block manifest, include the landing_gallery_cards extension.
The minimal configuration is as follows:
'assets' => [
'ext' => ['landing_gallery_cards'],
],<div class="js-gallery-cards">
<img class="landing-block-node-card-img" src="/upload/gallery-1.jpg" data-fancybox="gallery" alt="">
</div>The landing_gallery_cards extension prepares images within js-gallery-cards for viewing in gallery mode and creates a clickable <a> wrapper around the image. When opened, the image from src is used. If the node has a srcset, it is also passed to the viewing settings.
The root container of the gallery must have the class js-gallery-cards.
Inside the container, image nodes of type img are placed. For each image, specify:
data-fancybox— an indicator of participation in the gallerysrc— the source of the image that will open upon clicking
Optionally:
data-link-classes— classes that are added to the wrapper link around the image, for example,d-block g-pos-rel
Example:
<div class="js-gallery-cards row">
<div class="landing-block-node-card col-lg-3 col-md-4 col-sm-6 g-mb-30">
<img
class="landing-block-node-card-img g-max-width-100x g-max-height-350"
src="https://cdn.bitrix24.site/bitrix/images/landing/business/270x481/img1.jpg"
data-fancybox="gallery"
data-link-classes="d-block g-pos-rel"
alt="">
</div>
<div class="landing-block-node-card col-lg-3 col-md-4 col-sm-6 g-mb-30">
<img
class="landing-block-node-card-img g-max-width-100x g-max-height-350"
src="https://cdn.bitrix24.site/bitrix/images/landing/business/270x481/img2.jpg"
data-fancybox="gallery"
data-link-classes="d-block g-pos-rel"
alt="">
</div>
</div>The gallery can be used together with a slider. In this case, it is important to include the extensions in the following order:
landing_carousellanding_gallery_cards
'assets' => [
'ext' => ['landing_carousel', 'landing_gallery_cards'],
],- The image must have a
srcspecified; otherwise, the wrapper link will not be created. - To participate in the gallery, the node must have the
data-fancyboxattribute. - In the basic scenario, the gallery opens the image from
src; a separate field for the thumbnail/full version pair is not used. data-link-classesis applied to the created wrapper link around the image.- When used together with a slider, first include
landing_carousel, thenlanding_gallery_cards.
