Hi Chris, there is no option within the theme which switches it to a grid view, so it would require customization on your part if you were looking to change the layout this way. There is also no existing child theme for Vantage available in the
AppThemes marketplace at this time. AppThemes does not officially support customizations, so unfortunately no there is no documentation which would guide you through these changes, but it is possible as you can see from some examples in the
AppThemes customer showcase. We also do have a Vantage General Discussion forum where you can seek community based support. We do not offer customization services, however we do have a
certified partners page where you can find developers for hire if you are looking for someone to make these layout changes for you. If you make contact directly with an outline of your requirements, they can provide a quote for the work. Thanks.
