Filter with checkbox

-- HikaShop version -- : 4.0.1

Hello,

Hope that I can put my question here.
I want to use a filter with some checkbox(es).
This I have tested local before I do this live.

Now I have all the checkbox(es) in a vertical line
But I want these in a horizontal.
In all possible options in Hikashop I can't find the possibilty to do this.
How can I achieve this in the best way?

I have looked in this category of the forum if my question is there but I cant find an answer

Kind regards
