1. New "Nhip song" (I created it)


2. "K2" (already in simple template)


Hi, my problem is when I created a new menu name, it appeared a small distance but big problem. I cannot choose submenu.
- First image has a distance between mainmenu and submenu, pay attention a red line I drawed.
To help you more understand, this is a link i4u.vn, choosing "Nhip song" and k2 to know my problem clearly.

Thanks.

I am sorry but this is not related to K2. This is a template specific CSS issue.

You need to ask the template developer about this issue.
