How To Show Selected Variant Images [Dawn 14.0.0]

Step 1: Schema In main-product.liquid File

Add the following schema code in main-product.liquid file

 ,
{
      "type": "header",
      "content": "Selected Variant Images"
    },
     {
        "type": "paragraph",
        "content": "Subscribe our channel [websensepro](https:\/\/youtube.com\/@websensepro?sub_confirmation=1)"
      },
    {
      "type": "checkbox",
      "id": "enable_group_media",
      "label": "Enable Selected Variant Images",
      "default": false
    },
    {
      "type": "text",
      "id": "media_grouping_option",
      "label": "Selected Variant Option Name",
      "default": "Color",
      "info":"Attach the first image of each group of variant media to a variant."
    }

Step 2: Update global.js

Add the following code with in updateMedia() function:

// Selected Variants Code
    const variantValues = this.currentVariant.options
    const mediaGallery = document.querySelector(`[id^="MediaGallery-${this.dataset.section}"]`)
    if (mediaGallery.hasAttribute("image-grouping-enabled")) {
      mediaGallery.querySelectorAll('[data-image-group]').forEach(el => el.classList.add('hide-media'))
      variantValues.forEach(value => { mediaGallery.querySelectorAll(`[data-image-group="${value}"]`).forEach(el => el.classList.remove('hide-media')) })
      mediaGallery.querySelectorAll('slider-component').forEach(slider => { slider.initPages() })
    }
    // Selected Variants Code end

Step 3: Replace product-media-gallery.liquid File Code:

Replace product-media-gallery.liquid file code with the following code:

{% comment %}
  Renders a product media gallery. Should be used with 'media-gallery.js'
  Also see 'product-media-modal'

  Accepts:
  - product: {Object} Product liquid object
  - variant_images: {Array} Product images associated with a variant
  - is_duplicate: {Boolean} Prevents rendering uneeded elements and duplicate ids for subsequent instances

  Usage:
  {% render 'product-media-gallery', is_duplicate: true %}
{% endcomment %}
