With the Shuffle Filter feature, you can show categories, tags and custom taxonomies as options in several types to filter result. When you show options as checkboxes, the scrollbar will be shown if there are a lot of options.
To show all options without scrollbar, Please add this code to Custom CSS field (the left textarea) in Content Views >> Settings page:
.pt-cv-filter-group ul {max-height: 500px;}
Best regards,
