Secondary Menus on a separate line

Is there anyone I can email about this theme? I found the spot in the CSS that’s causing the problem. It’s this:

.header-wrapper .main-navigation ul ul.sub-menu {
top: 50px;
}

The only problem is that if I take it out, the first sub-menu doesn’t skip to the next line. So there’s the main menu. When you hover over the main menu and there’s a submenu, a dropdown menu appears. That dropdown menu needs to be on the next line from the main menu. The problem is that when you hover over one of those items in the vertical menu, a menu should open up next to it, assuming there’s a third layer to the menu. This CSS is also causing that to drop down a line, making it impossible to navigate. In other words, if I remove that CSS, it fixes one thing but breaks something else. I really need help with this. I really love this theme and I’d even pay for the premium theme, but there’s just bugs.

Well, after experimenting with CSS for the last couple hours, I finally got it. It would appear that I can’t delete this post, but that’s OK because people will be able to learn from my problems, and this is a fairly major problem. Here’s what I added to the CSS:

.header-wrapper .main-navigation ul ul ul.sub-menu {
top: 0px;
}
