I am a new odoo user.

I have 3 websites on odoo. My goal is to create a field that allows to select multiple websites in the "website" field to create a filter by website for each product. There is already a "website_id" field but it only allows to select one website.

I managed to create many2many field (x_website_ids) and display it in the form, but the filter has no effect when visiting the website. The products are still displayed on all websites. Can you tell me what are the missing steps to make the filter work on the websites?

Thank you for your help.
