You are actually using the bootstrap classes which is causing the page to break once you have the 3rd item. Just having this only is sufficient for your view.
Thanks for your reply! Indeed now the three items are displayed correctly, but when you apply a filter eg "Carrière" picked and then push on the orange button. Then the issue is still there...
It seems that the layout within the divi layout is breaking the footer area that you made. Not sure why as i'm not so experienced on divi's css and templating structure.
The alternative that I would suggest is to build out your looped items manually by either using tables or using some custom responsive columns css.
Take a look at the link below. hidden link
This should be able to guide you on how to create the responsive css grid.
I really appreciate your support, but can you please escalate the issue to someone who has more experience on Divi in combination with Toolset please? Because when i just Googled i see there are many problems with views and Divi since they updated the theme...
The site normally goes live tomorrow and for now it's her already 10.10 pm. So there is not much time left to make significant changes to the layout.
Anyway, thanks for your support and very quick responses! I really appreciate that!
