Hi,
The best solution will be a product listing module.
But there is no vendor filter and it will be difficult for HikaMarket to synchronize the module with the JomSocial page because it has to determine the vendor.
We have in our todo list the idea to add such "vendor filter" but we are still seeing the best way to integrate it with HikaShop.

By the way, do not send me private message, use the "contact us" form instead.
