In mai main menu, i have 2 dropdown menus, and after i hover them, the whole menu get hide.
Can you give me a hint whay, and how to fix this?

Hi,

You have a display:none added to your main menu when the mouse goes outside the area:

It's probably done by your javascript for the menu.
Please use stackoverflow.com/ for such question, not related to HikaShop at all but to coding.
