Hi,
Only to help you with the wording for future communication: these bookmarks are commonly referred to as "tab", or plural "tabs" - related to "tabular".
For what you're up to (and most if not everything else) you'll find articles and tutorials here in the -> Support -> Documentation part.
What you're looking for is here:
www.hikashop.com/support/support/documen...tml#display_products
So, change the parameter "Layout on product page" to... yup, you guessed right: "Tabular". Save, and reload a product page. Should work.
Note that this is then the default value - true for all products if you, as you come across a field with the same title, leave such settings at "Inherit".
