Where Do I Find Out The "more" Option To Customize In Product Page

Where do I find out "More" option in product detail page to customize it according to my need. Please see the screenshot. I show this option earlier but can't find it now anyhow! please help. Actually I want to hide "More" option so that visitors can see post details by default without clicking More text.


This feature is added by 3rd party theme on your store. Contact theme developers for details

Got it. Thanks
