Hi!
1. Can I take a look at this issue somewhere? I just tried the search on this page, but I am able to scroll without any problems there. I guess you might have switched the layouts, so the issue is no longer present(?).
2. I think this is due to the filter boxes exceeding the default max-height value, so the scrollbar is triggered to be visible. I recommend two things here:
I.) Changing the max-width of the filter boxes to ‘none’ here.
II.) Turning off the scrollbar script, as you probably doesn’t need it whatsoever.
These should get rid off those.
3. Well, it depends on the order of the filters, as well as on the layout of the filter boxes and the column count.
4. Centering them is only possible via custom CSS, the filters will automatically follow the page direction. For most cases, this custom CSS should do the trick:
.asp_sb_1 {
margin: 0 auto !important;
}
