Reverse Column Order is an add-on for WPBakery Page Builder
(js_composer). WPBakery stacks a row’s columns top-to-bottom in
the same order as they appear left-to-right on desktop.
This plugin adds a single checkbox, “Reverse column order on stack
(mobile/tablet)”, to the WPBakery Row and Inner Row edit forms. When
checked, that row’s columns are shown in reverse order once they stack,
for example, showing a text column above an image column on mobile, even
though the image column comes first on desktop.
