For creating subdomains for localhost you just need to follow 2 simple steps.

Open your terminal by pressing CTRL + ALT + T then run the following commands:

sudo vi hosts
sudo -i gedit /etc/hosts # to edit /etc/hosts file

Once you run 2nd command /etc/hosts file will open and now this is the place where you need to define subdomains.

Example: localhost is:

127.0.0.1       //our localhost

define new subdomain:
127.0.0.1       example.localhost   # first

and another..

127.0.0.1       demo.localhost      #second

that's it. Hope this was helpful.
