Grouped Product Filter is the perfect solution to long lists of child products on your Grouped Product pages! It creates drop down filters based on the child products’ attributes that quickly and easily filter the product list to allow your buyer to determine which product they need, with ease.
This Magento 2 module also has a bit of intelligence built into it. What does that mean? It means that it only creates a filter when it needs one. For example, when all of the child products have the same value(s) for a particular attribute, no filter is needed because they are all the same. Also, this extension does not override your grouped product template file, it will work with whatever template you are currently using, whether it is Magento’s native template file or a custom one.
Additionally, you can set the sort order of the child products to sort by name, price, or sku for your convenience. You can also customize the colors of the ajax spinner to match your theme.
