Hello, Marta,
Thank you for getting in touch with us.
You can activate “Show Variations As Simple Products” in Theme options > WooCommerce > Shop > Products style – https://prnt.sc/G5YrAq8dVdgE
If this does not meet your needs, you may wish to consider using an additional plugin. Please note that we cannot guarantee full theme compatibility with all existing plugins, and we have not tested plugins with the specified functionality, unfortunately.
Kind Regards,
8theme team
