Default attribute plugin

Hi there,

> For this moment, we use Load Group Attributes Product but the plugin is not any more released since three years.

It looks like that plugin page also includes a link to where you could purchase a version of the plugin that may be more up to date: https://www.zhaket.com/web/fast-attributes-woocommerce-plugin

> We bought WooCommerce Group Attributes but when install it, we see that the front-end design of the list of attributes is changed, so that its impossible to read correctly the attributes.

I recommend reaching out to their support as they may be able to help you troubleshoot/customize the functionality you’re looking for for your site:

Are you looking to add default attributes to the front end? If so, there are a few ways to add this functionality to your site. I recommend checking out tutorials like this one:

Or are you wanting to add default attributes to the edit product page? If you are technically minded, this custom code may also help:

Customizations can be done via a functionality plugin (https://css-tricks.com/wordpress-functionality-plugins/). This is a simple plugin that contains anything you would otherwise paste in functions.php and it is advantageous because it’s theme-independent.

If the available solutions are not giving you the functionality you’re looking for or if it’s outside of your comfort zone, you may also want to look into hiring a developer. In that case, we can recommend contacting one of the services on our WooCommerce Customizations Page.
