Menu Bar

Hello, so I have problem with my menu bar, when I open my website on computer/laptop(on mobile phones it works well) and point on categories O ŽUPI, ZAJEDNICE and others, subcategories dropdown is not working well. You can see that on link of my website. I don't know how to fix that problem so I could use some help. Thank you for your help link to page: http://www.zupa-bezgresnog-zaceca-bdm.hr Regards, Filip
