Hope it helps
Thank you for the suggestion! This idea will actually be very useful for different pages within my site, however, it doesn't achieve what I needed for the product description.
The tabs i currently have (blue arrows), when clicked, change the whole product description rather than just scrolling down to a specific section... I would like to add another tab like the ones i currently have (where yellow arrows are).
I found how to add the "size guide" tab directly in the customize section of the store, but it only allows for one extra tab.
I understand. you can achieve this by custom code in liquid. DM me if you would like to get this done
