How do I create a new sub domain?
A subdomain is a subsection of your website that can exist as a new website without a new domain name. Use subdomains to create memorable URLs for different content areas of your site. For example, you can create a subdomain for your blog that is accessible through blog.example.com and www.example.com/blog.
At the subdomain field, enter the name for your subdomain and select the domain at the Domain field.
The document root will be automatically generated with the subdomain name. The system will create this folder for you.
