How to add scroll bar to filter section

Hey, it is not super obvious that for the brand filter, there is actually more brands there to filter from, the person just needs to scroll down whilst there mouse is over that section. So I would like to know, can anyone recommend a good way to add a scroll bar or something to that filter, so it is more obvious to people there are more brands to filter from.

You can do this with CSS, just put this into Section “Custom CSS” setting:

.facets--horizontal .facets__inputs-wrapper {
  scrollbar-width: auto;
}

clean, easy, and simple, you sir are a legend, thank you so much!
