Q: What is the best way to set up the side bar filters? So far the options available are “by tag” (which produces a long and not-searchable list) and “by group” (this is by fitment group).  Or is this something that would need to be manually edited? 

A: We don’t know because we’re not web developers. But we have heard good stories about plugins like Mega Menu. There are also Shopify themes that have different navigation and filtering options.
