[Plugin: WordPress Menu Creator] Widget -How to?

I’m in the middle of creating a vertical drop menu that I want to put in a widget in a sidebar, but I haven’t been able to find any instructions particular to widget use. Here are my questions:

What do I enter for: Menu wrapper top? Menu wrapper bottom?

Also, if the menu is going to appear in a widget, where do I place the php code?

As it happens, my theme, Atahualpa 3.4.2, doesn’t have a sidebar.php file, and the coding for the built in menus (horizontals that appear below the header) are in their own files (e.g. bfa_hor_pages.php).

Thanks in advance.
