Struggling to make element scroll horizontally

Hello there !

I’ve been struggling to make my div scroll horizontally even though all parents div/containers’s width are set to 100%. As anyone had a similare issue ?

Here is a screen for reference !

I may had that I’m trying to make everything scroll over the elements of my collection

Hello @JacquesL,
try to do it this way

Hey ! Thanks it worked just fine. But do you know why letting the div that contains the collection on auto makes it work ? I had it on 100% width
