We are using Flickity in this case to create our awesome product image slider.
Go to your Shopify theme code editor, scroll down to the Asset folder and create a .js file and name it flickity then create a .css file and name it flickity aswell. You should now have 2 files flickity.js and flickity.css.
{{ 'flickity.css' | asset_url | stylesheet_tag }}
{{ 'flickity.js' | asset_url | script_tag }}
Change Main-Product.Liquid
Now head over to the Section folder and find main-product-liquid, now here is the focus part, find the below code.
<div class="grid__item product__media-wrapper">
<slider-component class="slider-mobile-gutter">
<a class="skip-to-content-link button visually-hidden" href="#ProductInfo-{{ section.id }}">
{{ "accessibility.skip_to_product_info" | t }}
</a>
<ul class="product__media-list grid grid--peek list-unstyled slider slider--mobile" role="list">
{%- assign variant_images = product.images | where: 'attached_to_variant?', true | map: 'src' -%}
{%- if product.selected_or_first_available_variant.featured_media != null -%}
{%- assign media = product.selected_or_first_available_variant.featured_media -%}
<li class="product__media-item grid__item slider__slide{% if media.media_type != 'image' %} product__media-item--full{% endif %}{% if section.settings.hide_variants and variant_images contains media.src %} product__media-item--variant{% endif %}" data-media-id="{{ section.id }}-{{ media.id }}">
{% render 'product-thumbnail', media: media, position: 'featured', loop: section.settings.enable_video_looping, modal_id: section.id, xr_button: true %}
</li>
{%- endif -%}
{%- for media in product.media -%}
{%- unless media.id == product.selected_or_first_available_variant.featured_media.id -%}
<li class="product__media-item grid__item slider__slide{% if media.media_type != 'image' %} product__media-item--full{% endif %}{% if section.settings.hide_variants and variant_images contains media.src %} product__media-item--variant{% endif %}" data-media-id="{{ section.id }}-{{ media.id }}">
{% render 'product-thumbnail', media: media, position: forloop.index, loop: section.settings.enable_video_looping, modal_id: section.id, xr_button: true %}
</li>
{%- endunless -%}
{%- endfor -%}
</ul>
<div class="slider-buttons no-js-hidden{% if product.media.size < 2 %} small-hide{% endif %}">
<button type="button" class="slider-button slider-button--prev" name="previous" aria-label="{{ 'accessibility.previous_slide' | t }}">{% render 'icon-caret' %}</button>
<div class="slider-counter caption">
<span class="slider-counter--current">1</span>
<span aria-hidden="true"> / </span>
<span class="visually-hidden">{{ 'accessibility.of' | t }}</span>
<span class="slider-counter--total">{% if section.settings.hide_variants %}{{ product.media.size | minus: variant_images.size | plus: 1 }}{% else %}{{ product.media.size }}{% endif %}</span>
</div>
<button type="button" class="slider-button slider-button--next" name="next" aria-label="{{ 'accessibility.next_slide' | t }}">{% render 'icon-caret' %}</button>
</div>
</slider-component>
{%- if first_3d_model -%}
<button
class="button button--full-width product__xr-button"
type="button"
aria-label="{{ 'products.product.xr_button_label' | t }}"
data-shopify-xr
data-shopify-model3d-id="{{ first_3d_model.id }}"
data-shopify-title="{{ product.title | escape }}"
data-shopify-xr-hidden
>
{% render 'icon-3d-model' %}
{{ 'products.product.xr_button' | t }}
</button>
{%- endif -%}
</div>
Delete everything between the parent <div> so all you are left with is the below code
<div class="grid__item product__media-wrapper">
PASTE NEW CODE HERE
</div>
Then, paste the below code inbetween where it says “PASTE NEW CODE HERE”
{% if product.images != null %}
<div class="carousel product__image-slider" role="document" aria-label="{{ 'products.modal.label' | t }}" tabindex="0">
{%- for media in product.media -%}
<div class="carousel-cell">
{% if media.media_type == "video" %}
{{ media | media_tag: image_size: "720x", autoplay: true, loop: loop, controls: true, preload: "none", autoplay: true, height: "100%", width: "100%" }}
{% else %}
<img data-flickity-lazyload-srcset="
{{ media | img_url: '1440x' }} 1440w,
{{ media | img_url: '1080x' }} 1080w,
{{ media | img_url: '720x' }} 767w,
{{ media | img_url: '480x' }} 480w"
sizes="(min-width: 480px) 1440px, 1080px, 767px, 480px"
data-flickity-lazyload-src="{{ media | img_url: 'master' }}"
alt="{{ media.alt | escape }}"
border="0"
data-media-id="{{ media.id }}" />
{% endif %}
</div>
{%- endfor -%}
<!--- Coded by bluish.io --->
</div>
{% if product.images.size > 1 %}
<div class="carousel product__image-thumbnail">
{%- for media in product.media -%}
<div class="carousel-cell">
<img data-flickity-lazyload-srcset="
{{ media | img_url: '1440x' }} 1440w,
{{ media | img_url: '1080x' }} 1080w,
{{ media | img_url: '720x' }} 767w,
{{ media | img_url: '480x' }} 480w"
sizes="(min-width: 480px) 1440px, 1080px, 767px, 480px"
data-flickity-lazyload-src="{{ media | img_url: 'master' }}"
alt="{{ media.alt | escape }}"
border="0"
data-media-id="{{ media_id }}" />
</div>
{%- endfor -%}
<!--- Coded by bluish.io --->
</div>
{% endif %}
{% else %}
{{ 'product-1' | placeholder_svg_tag }}
{% endif %}
Now scroll down the file until you find the {% schema %} tag, right above that line, paste the below code
<script>
var elem = document.querySelector('.carousel.product__image-slider');
var flkty = new Flickity( elem, {
contain: true,
imagesLoaded: true,
lazyLoad: 1,
wrapAround: true,
pageDots: false,
{% if product.images.size < 2 %}
prevNextButtons: false,
{% endif %}
adaptiveHeight: true
});
var elemThumbnail = document.querySelector('.carousel.product__image-thumbnail');
var flktyB = new Flickity( elemThumbnail, {
asNavFor: '.carousel.product__image-slider',
contain: true,
imagesLoaded: true,
lazyLoad: 4,
pageDots: false,
prevNextButtons: false
});
</script>
Add Code to Base.css
Go to your main css file, in this case we are using the Dawn theme, so the main css file is base.css, at the end of the file paste the below code.
.product__image-slider {
width: 100%;
}
.product__image-slider .carousel-cell {
width: 100%;
height: auto;
margin: 0 5px
}
.product__image-slider .carousel-cell img {
width: 100%;
height: 100%;
}
.grid__item .product__image-slider {
margin-bottom: 2rem;
}
.product__image-slider .flickity-viewport {
transition: height 0.2s;
}
.flickity-button:disabled {
display: none;
}
.product__image-thumbnail .carousel-cell {
width: 20%;
margin-right: 10px;
}
.product__image-thumbnail .carousel-cell img {
width: 100%;
height: 100%;
}
@media screen and (min-width: 990px) {
.product:not(.product--no-media):not(.featured-product) .product__media-wrapper {
max-width: 50% !important;
width: calc(50% - 1rem / 2) !important;
}
.product:not(.product--no-media):not(.featured-product) .product__info-wrapper {
max-width: 50% !important;
width: calc(50% - 1rem / 2) !important;
}
}
Change Global.js
Almost done! In the same asset folder as base.css, find global.js, within the file, find the below code.
constructor() {
super();
this.addEventListener('change', this.onVariantChange);
}
Replace the above with the below code
constructor() {
super();
this.initLoad();
this.addEventListener('change', this.onVariantChange);
}
initLoad(){
this.updateOptions();
this.updateMasterId();
this.updateMedia();
}
Then within the same file, find the below code.
updateMedia() {
if (!this.currentVariant) return;
if (!this.currentVariant.featured_media) return;
const newMedia = document.querySelector(
`[data-media-id="${this.dataset.section}-${this.currentVariant.featured_media.id}"]`
);
if (!newMedia) return;
const modalContent = document.querySelector(`#ProductModal-${this.dataset.section} .product-media-modal__content`);
const newMediaModal = modalContent.querySelector( `[data-media-id="${this.currentVariant.featured_media.id}"]`);
const parent = newMedia.parentElement;
if (parent.firstChild == newMedia) return;
modalContent.prepend(newMediaModal);
parent.prepend(newMedia);
this.stickyHeader = this.stickyHeader || document.querySelector('sticky-header');
if(this.stickyHeader) {
this.stickyHeader.dispatchEvent(new Event('preventHeaderReveal'));
}
window.setTimeout(() => {
parent.scrollLeft = 0;
parent.querySelector('li.product__media-item').scrollIntoView({behavior: 'smooth'});
});
}
Replace the above with the below code, this will allow flickity to change image when you select a variant, if the variant has a featured image set in your product section.
updateMedia() {
if (!this.currentVariant) return;
if (!this.currentVariant.featured_media) return;
var current_media_id = this.currentVariant.featured_media.id;
// For product page with flickity
if (document.querySelector('.product__image-slider')) {
var media_len = document.querySelector('.product__image-slider .flickity-slider').childElementCount;
var media_id_array = [];
for (let i = 0; i < media_len; i++) {
media_id_array.push(parseInt(document.querySelector('.product__image-slider').querySelectorAll("img")[i].getAttribute('data-media-id')));
}
flkty.select(media_id_array.indexOf(current_media_id));
}
// For featured products on homepage without flickity
else if (document.querySelector('.product__media-list')) {
var featured_product_media_len = document.querySelector('.product__media-list').childElementCount;
for (let i = 0; i < featured_product_media_len; i++) {
var child = document.querySelector('.product__media-list').children[i];
if (child.getAttribute('data-media-id').indexOf(current_media_id) > 0) {
child.style.display = "block";
} else {
child.style.display = "none";
}
}
}
}
And you’re done! You now have an awesome product image slider for your Dawn theme.
