Thanks for the reply.
We need to implement a module or component for Joomla 3 .. that allows the site visitor the choice to accept or reject all or part of the cookies according to European legislation.
As for example you can see on this site: https://www.iodonna.it/moda/
We already have our own banner, but it does not comply with European legislation as it does not allow you to choose your preferences:
https://www.inastri.com/
I enclose 2 Photos of how to behave the banner both at the time of access and at the time of choosing preferences.
Something like this is fine too.
Thank you
