Has anyone been able to achieve a dynamic header based on the chosen category selected by the user. Basically if a user selects Spas I would have a header themed with a spa image. If the user selects saunas then the header would have sauna imagery.
You may add code to check a category name in Header code file. When a user select, code in header the name check process. e.g. if select category name "A" --> change css class to "StyleA". if select category name "B" --> change css class to "StyleB".
