If you have a lot of options, it will be friendly to show options in 2 columns, to help visitors to select filters without scrolling too much.
To do it, please add this code to Custom CSS field in Content Views >> Settings page:
.pt-cv-wrapper [id^="pt-cv-filter-bar-VIEWID"] >.dropdown-menu {min-width:400px} .pt-cv-wrapper [id^="pt-cv-filter-bar-VIEWID"] ul.dropdown-menu li {width:48%!important;display:inline-block}
(replace VIEWID with ID of your View).
To make it works with ALL dropdown filters, please use this code instead:
div.pt-cv-wrapper .pt-cv-filter-bar >.dropdown-menu {min-width:400px} div.pt-cv-wrapper .pt-cv-filter-bar ul.dropdown-menu li {width:48%!important;display:inline-block}
Best regards,
