Displaying related categories instead brands

If you set the "Synchronize with currently displayed item when possible" = YES - displaying related categories instead related brands. Screen shot of settings attached.

Is it possible to configure so that when you select a category in the module display a list of brands associated with the product brands, and the choice of the brand in the module display a list of categories related to the product categories ?

The synchronization option will only work when you're displaying a listing of products or a listing of categories in the main area of your website. In that case, the module will use the parent category of these categories/products as basis for its own display of categories. The module will however ignore that option for brands.

If you want to change that behavior, you would have to implement the onBeforeCategoryListingLoad trigger via a hikashop plugin to modify the query loading the categories/brands (clearly not easy).
