Multi product domains

[luke_devon]

Hi 

 

I want to publish more product domain in a single web domain . 

 

For example :

 

If my web domain is www.somethig .com , and I have Cosmetics, Electronics, Sport items and Auto spare parts as my product categories , how can I publish them in the www.something.com domain ?

 

Can we create multi-sites in a single web domain ?   what is the best practice for such a situation with prestashop ?

 

Please guide me to optimize the prestashop for the above requirement.

 

Thanks in advance

Luke.
