Thanks . I want the default customizer page of a visual products customizer plugin I’ve purchased and installed, customised. Basically, the default page is formatted in two column groups with a div.shop-filter_component on the left and a div.shop-filter_viewport on the right. I want to have an additional central column group, which will serve as a container for three possible pane options (which relate to the components in the shop-filter), plus an image zoom on hover outside the central column. Hope my overview is clear?
