I took a look at the page. The categories list from the Enhanced Categories extension is designed to output in columns already. I see that it is on your site. The issue is the design is not to spread children categories across columns because the hierarchy is very hard to discern when it is allowed.

That said, I see since you have only two category parents with one containing the majority it does create quite a lopsided display. So, try adding this to the theme’s custom CSS area.

ul.cn-category-list-container li {
    page-break-inside: auto;
    break-inside: initial;
}

This should allow the categories to display in columns regardless of placement in the hierarchy.

Hope that helps!
