Currently, all variants are displayed on the article. However, if the articles are split in the listing, you will see all variants multiple times. Once as a single article and once as a variant selector.

Here an option would be helpful, which shows only the variant attributes on the article for selection, which are not already split. In this example, in the category the variants are split by color and the sizes are available for selection:

It would be a nice feature if there would be also a option for show all variants and those ones who are out of stock would be grayed out or disabled.

As seen on the issue tracker: https://issues.shopware.com/issues/NEXT-15280

On Shopware 6.4.12 there seems to be a compatibility issue:

request.CRITICAL: Uncaught PHP Exception TypeError: "SasVariantSwitch\Storefront\Page\ProductListingConfigurationLoader::isCombinable(): Argument #3 ($combinations) must be of type Shopware\Core\Content\Product\SalesChannel\Detail\AvailableCombinationResult, null given, called in /www/htdocs/w007fddd/[shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php](http://shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php) on line 72" at /www/htdocs/w007fddd/[shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php](http://shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php) line 280 {"exception":"[object] (TypeError(code: 0): SasVariantSwitch\\Storefront\\Page\\ProductListingConfigurationLoader::isCombinable(): Argument #3 ($combinations) must be of type Shopware\\Core\\Content\\Product\\SalesChannel\\Detail\\AvailableCombinationResult, null given, called in /www/htdocs/w007fddd/[shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php](http://shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php) on line 72 at /www/htdocs/w007fddd/[shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php:280](http://shop.easy-to-run.de/custom/plugins/SasVariantSwitch/src/Storefront/Page/ProductListingConfigurationLoader.php:280))"} []

Problem description

On the product list all variants are shown, including those that have been excluded for the current sales channel. The product detail page shows only variants which are actually visible for the current sales channel.

Steps to reproduce

1. Create two sales channels, for example pointing to different subdomains.
2. Create a product with a few variants.
3. For a certain variant change visibility, removing one sales channel.
4. See the behavior:
   1. Open product list to see it still shows the variant that should be hidden now.
   2. When switching to this variant the entire product is hidden.
   3. When opening the product detail page the variant is not shown.

in one of our Shopware 6 shops we have two other plugins active in addition to your plugin.

That would be “shopping cart free products / goals | by 28minds” and “Award Items”. As soon as a free product or a bonus item (using these plugins) is placed in the shopping cart, your plugin will issue an error message. In the CartPageLoadedSubscriber.php file, in line 122 of the addLineItemPropertyGroups function, the $lineItem parameter is set to zero, which leads to an error. Would it be an option here to include an if statement that checks whether $lineItem !== is null?

When in the for loop of creating the option elements for the select of the variants, please add the productNumber association for the option group so the productNumber is assigned to the option as well, or to the option's product.
