I'd like to add a menu to the odoo site. I wanted to inject the new item directly into model.website, but I've noticed that it persists in the database and if I change the url, I have to raze everything before it takes. I read somewhere that I could do template inheritance, but I don't understand how it works. I've looked through articles without really understanding. I still have this error, but when I go to the browser inspector, I can see this class.

Error : "RPC_ERROR
