I changed also the way to select form from :

$('form[action="/cart/add"]')

to

$('form[action*="/cart/add"]')

Because when you are on a locale (/en), it does not match, and it should !

+1 for @Sanjayavidbrio's solution found here: https://belvg.com/blog/shopify-variants.html#step_5! However, if you want to still show products that you do carry, but are out of stock, this will not work out of the box.

My goal was to remove variant combonations that we just do not carry, but if we have a variant that is Out of Stock, we still want to show that. Below is my linked-options.liquid snippet file.

<script>
window.addEventListener('DOMContentLoaded', function() {
  var Shopify = Shopify || {};
    
  // Required functionality from depricated options_selection.js
  Shopify.arrayIncludes = function(e, t) {
    for (var n = 0; n < e.length; n++)
        if (e[n] == t) return !0;
    return !1
  }, Shopify.uniq = function(e) {
      for (var t = [], n = 0; n < e.length; n++) Shopify.arrayIncludes(t, e[n]) || t.push(e[n]);
      return t
  }

  Shopify.optionsMap = {};

  Shopify.updateOptionsInSelector = function(selectorIndex) {
      
    switch (selectorIndex) {
      case 0:
        var key = 'root';
        var selector = jQuery('.single-option-selector:eq(0)');
        break;
      case 1:
        var key = jQuery('.single-option-selector:eq(0)').val();
        var selector = jQuery('.single-option-selector:eq(1)');
        break;
      case 2:
        var key = jQuery('.single-option-selector:eq(0)').val();  
        key += ' / ' + jQuery('.single-option-selector:eq(1)').val();
        var selector = jQuery('.single-option-selector:eq(2)');
    }
    
    var initialValue = selector.val();
    selector.empty();    
    var availableOptions = Shopify.optionsMap[key];
    for (var i=0; i<availableOptions.length; i++) {
      var option = availableOptions[i];
      var newOption = jQuery('<option></option>').val(option).html(option);
      selector.append(newOption);
    }
    jQuery('.swatch[data-option-index="' + selectorIndex + '"] .swatch-element').each(function() {
      if (jQuery.inArray($(this).attr('data-value'), availableOptions) !== -1) {
        $(this).removeClass('soldout').show().find(':radio').removeAttr('disabled','disabled').removeAttr('checked');
      }
      else {
        $(this).addClass('soldout').hide().find(':radio').removeAttr('checked').attr('disabled','disabled');
      }
    });
    if (jQuery.inArray(initialValue, availableOptions) !== -1) {
      selector.val(initialValue);
    }
    selector.trigger('change');
    
  };

  Shopify.linkOptionSelectors = function(product) {
    // Building our mapping object.
    for (var i=0; i<product.variants.length; i++) {
      var variant = product.variants[i];

        // Gathering values for the 1st drop-down.
        Shopify.optionsMap['root'] = Shopify.optionsMap['root'] || [];
        Shopify.optionsMap['root'].push(variant.option1);
        Shopify.optionsMap['root'] = Shopify.uniq(Shopify.optionsMap['root']);
        // Gathering values for the 2nd drop-down.
        if (product.options.length > 1) {
          var key = variant.option1;
          Shopify.optionsMap[key] = Shopify.optionsMap[key] || [];
          Shopify.optionsMap[key].push(variant.option2);
          Shopify.optionsMap[key] = Shopify.uniq(Shopify.optionsMap[key]);
        }
        // Gathering values for the 3rd drop-down.
        if (product.options.length === 3) {
          var key = variant.option1 + ' / ' + variant.option2;
          Shopify.optionsMap[key] = Shopify.optionsMap[key] || [];
          Shopify.optionsMap[key].push(variant.option3);
          Shopify.optionsMap[key] = Shopify.uniq(Shopify.optionsMap[key]);
        }

    }
    // Update options right away.
    Shopify.updateOptionsInSelector(0);
    if (product.options.length > 1) Shopify.updateOptionsInSelector(1);
    if (product.options.length === 3) Shopify.updateOptionsInSelector(2);
    // When there is an update in the first dropdown.
    jQuery(".single-option-selector:eq(0)").change(function() {
      Shopify.updateOptionsInSelector(1);
      if (product.options.length === 3) Shopify.updateOptionsInSelector(2);
      return true;
    });
    // When there is an update in the second dropdown.
    jQuery(".single-option-selector:eq(1)").change(function() {
      if (product.options.length === 3) Shopify.updateOptionsInSelector(2);
      return true;
    });  
  };
   
  {% if product.available and product.options.size > 1 %}
    var $addToCartForm = $('form[action="/cart/add"]');
    if (window.MutationObserver && $addToCartForm.length) {
      if (typeof observer === 'object' && typeof observer.disconnect === 'function') {
        observer.disconnect();
      }
      var config = { childList: true, subtree: true };
      var observer = new MutationObserver(function() {      
        Shopify.linkOptionSelectors({{ product | json }});
        observer.disconnect();
      });  
      observer.observe($addToCartForm[0], config);
    }
  {% endif %}
    
  var selector = jQuery('.single-option-selector:eq(0)');
  selector.trigger('change'); 

});
</script>

The key differences are to remove the if (variant.available) { } located at line 61 (and the closing } on line 80). Then I remove the entire chunk from line 117-124 that deals with products with only one option size.

Hope this help someone else!

@robhuska thanks for your solution that was does not work for me.

First you need to convert dropdown into swatches.

There is already tutorial for it.

So go and implement that first and then try to understand what bug or code you need to fix in linked option to make it work.

I explained in my screenshot.

Hello @YahyaYavuz61

This tutorial does not work directly for Prestige theme. Not for old version of Prestige theme too.

You will have to update product-form.liquid file first. You will have to call product options in dropdown and have to keep them hide. You have to update Classes assign to Swatches.
Then You will have to update this snippet and then it will work. There are numerous steps to implement linked-options for Prestige theme in shopify.

The code sort of works.
It works in cases when there are 10-15 variants with 3 variant options, but when the varaint quantity increases to 30+ it does not work properly.
Is there a way to solve this?

Edit:
With 2options it works perfectly, but when 3rd option is added the functionality breaks
