Hello,
HikaShop do not have such "navbar" feature ; but you can use Joomla plugins/component dedicated on the "menu" features (like maximenu, or else) which could provide you that specific feature and a compatibility with HikaShop.
Otherwise, it would require you to perform some deep customization using view override (and custom HTML/JS/CSS) in order to achieve such kind of display.
Please understand that the HikaShop support team is not specialized in customization ; but only to help regarding the usage and the understanding of HikaShop.
Regards,
