Can not create sub-categories

Hi there.
I use the Photoraphy Theme.
In my Portfolio Posttype I want to use categories and sub-categories.
But I cannot create sub-categories. Why isn’t it possible to create sub-categories?
How can I?

Still need your help.
I don’t know, why it is not possible to create categories and sub-categories :frowning:

Hi Laloo83,

You should consider contacting theme Author directly, this is official Envato discussion board… Please find your purchased theme by its’ name in WordPress category and ask for support either in Comments section or Support tab:
