Hi, i want to setup a website on a server which have 3 databases, i know i can hide database selector and filter database in config file, but i need internal users have the ability to select other databases (test one, and another not related with the main one), but website should always be shown for external users and they only can login to make purchases.

Also on the main database, the company is not the one which should sell products on database, i mean, products are from the main company, but the website should be sell by another company. Should i just create another company to sell the producs? how can i configure the second company to be the one shown in website (logo, address, contact, etc)

PS: Odoo 10 version

Thanks in advance
