How do I add more than 1menu on the theme

I want to add another menu above the slider how do i do that only the menus are going below the slider, and how to get rid of the sample page above the slider?

Hi!
By default, there are two menus always visible on your screen, the "Main" menu and the "Top" menu. To customize any of them you have to go to the page Appearance => Menus and set the created menu as a main/top menu. Here are the intelligible instructions:

Removing the menus was discussed on our forum many times:
