Hello!
In the latest Hikashop-based e-store that I'm currently working on there are multiple categories nested inside each other (meaning - customer must select a brand, then a model, then a part type, and only then a product list appears). A challange that I'm now facing is that customer wants to have a slightly different layout for the model selection step (one of the categories).
I somehow assumed that it should be a piece of cake, given how flexible Hikashop platform is, and I included such design in my proposal, but now, actually setting this store up, I was bit surprised that there is no option for setting a custom class name for a particular category. 
Before I'm forced to write some kind of JavaScript based hack (something terrible like: "if category_title = "select model" then add class "model_selection_step" ), maybe there is some more elegant solution to this issue I'm facing? Many thanks in advance!
Best regards.
