Dawn theme first accordion open as default

[ChaletEtCeci]

Hi,

I would like my first accordion on my product page to be open as default.

I'm currently using dawn theme, I couldn't''t find the solution anywhere..

Also, in our brand page, I have a collection-list , I want to make it scrollable on pc showing only 4-5 items but scrollable to see more.

thank you
