Images Swatches – Tooltips
Similarly, when choosing the Image type for the swatches, users need to add a different image for each term to show as the thumbnail for the buttons in the frontend.
Users can choose to use the Tippy.js for the tooltips to show a more straightforward preview of variation with image, description & attribute terms in a bigger size. The description shown in the tooltip is the description of that attribute under Products >> Attributes.
