Universal Filter Sidebar List Format

I found the the element here : 

.custom-filter-container[class*="custom-filter-view-buttons"] .filterDropdown.sqs-block .archive-group-list li a {

And can modify in Custom CSS. Only a partial win, I'm cheating the vertical list format by giving each item a width, forcing it to stack, but the hover and click decoration now covers that width. I'll keep playing with it.

New issue that popped up is somehow all of my hyperlinks are not working and I have no idea why. But for anyone looking for modifying a Universal Filter format in Custom CSS, I inspected the page to track down the element above and I'm able to modify.
