Is your feature request related to a problem? Please describe.

Currently, there is no easy way to add 2 or more domains to one installed @joomla CMS.

Describe the solution you'd like

I propose to add a new setting to Joomla - to allow the CMS to work with two or more domains at the same time.

The following functions would be very helpful:

1. Ability to select a domain (or several domains) on which the Article will be published. With the option to select the main domain (for which there will be link rel=canonical)
2. Ability to select a domain (or multiple domains) on which the Category (and Tags) will be displayed. With the option to select the main domain (for which there will be link rel=canonical)
3. Ability to select a domain (or several domains) on which the Module will be published.
4. The ability to create a Home page for each domain related to CMS.
5. The ability to create any page in the site Menu (with the choice of one or more domains on which the menu item will be published)
6. Ability to select a default site Template for each domain (front-end)

General:

• One database for all domains
• One CMS setup for all domains
• One Control Panel for all domains
• A single database with users for all domains (users will not need to register again on another domain)

Additional context

I saw this announced for Joomla 4.2 This is a highly anticipated feature. I will be able to create networks of sites on similar topics.
