Hi,
I am talking about the Joomla menus ; it is related to Joomla configuration, not HikaMarket or HikaShop.
The fact that template A or template B is displayed is made by the Joomla core and the configuration is related to the Joomla menus. All is in the Joomla configuration side.
Now, in HikaMarket, you can force the usage of a specific menu for some internal links but that setting is available to the multi-vendor edition of HIkaMarket (because it is mostly used for the links of the vendor pages).
So if you want to force the menu, the best would be to add an entry in the HikaMarket configuration table.
namekey : vendor_default_menu
value : the Joomla menu item id
