How to create a subdomain in DirectAdmin

[indirectadmin]

Maybe a stupid question but I can not find the way to create a (working) subdomain in DirectAdmin.
Just adding an directory like in cpanel is not working.

Help would be appreciated.

Problem solved.
The hoster had not checked the subdomain option, so it was not visible.
