Eventure Theme : how to add an active tab

Hello

I purchased the Eventure theme and I am happy working on it. However, I have a question. How can I add one active tab to my postDetails like on the live preview of the Eventure theme (http://premium.themolitor.com/?theme=eventure)
I would like to have a tab with “Conditions”. Here is one example of a page I am working on:

Thanks in advance if somebody can help me.

Cheers

It’s better to contact the author and ask help from them directly due to forum is general purposes but not for item support

Thanks for the answer…I finally found it
