Thanks, that works fine. Can you suggest a solution for this problem: because the drop down is only needed for one set of products which are within another category, I have to create a sub-category for the ones with the drop down then apply the custom field to that category. However, when displayed by "DIV" in the product listing the ones with a drop-down then display separately from their parent category.
I could solve this using Jquery by replacing them into the parent category and hiding the sub-category, however, I would prefer to do it with a Hikashop selection or in the back-end possibly with views. If there is no option for grouping sub-categories with their parent then which view would I edit if I have a "product listing" displayed by Type of Layout -> "DIV". I would basically check whether the category has sub-categories and if so add the sub-categories to the first level of the array that writes the DIV layout. Does this sound doable or should I stick with a jQuery hack?
Thanks.
