Hi Artery,

I have a feeling that this is about Itemids - i.e. "menu item ids"... there's the official Itemid that you get from the main menu item, but the mod_rokvirtuemart_categories module is not giving the same Itemid for the same category.

Some of the side menu modules don't handle the Itemids properly. I haven't worked with mod_rokvirtuemart_categories but I suspect that it's not using the same Itemid (if it's even using one at all) as the corresponding "real" menu that points to that vendor/shop/whatever.

This is a difficult problem. It's probably going to be hard for you to get the behaviour you need out of the module, unless there's some sort of parameter when setting it up, to force it to use certain Itemids.

Is there anything else that distinguishes one shop from the other? e.g. product categories? It *may* help to try to identify which shop you are in based on that category instead of the menus... although that gets tricky with checkout and other non-product-specific pages. (so maybe that's not a good idea after all, sorry).

I think it's going to come down to getting mod_rokvirtuemart_categories to use appropriate/distinct Itemids. Can you ask for some help with that on the Rockettheme forums?

Cheers,
Stephen
