Vertical Menu And Top Menu?

Does anyone know how to make a vertical menu after Top Menu? I can't figure it out. I added a menu called Additional Menu and added to layout but it's not working as expected.

It works on the demo

What do you mean by "not working as expected"?

Check out see how the top is part of menu I want it separate like u showed me

For example, add the following code to the CSS section of the Theme editor

.top-menu {
    padding-bottom: 20px;


You are welcome!
