Conditional dropdown menu with Antimatter

Hi all,

I enabled the dropdown option in the Antimatter theme to see the sub-menus on my navigation bar. However this is activated for all the menus while I don't want the dropdown to be activated for my "blog" entry since the list of sub-pages is pretty long there. How can I set what menu entry can have a dropdown?

Thanks!

The use of a digit prefix for a folder name makes a page visible in the menu also you can override this behavior by setting visible to true or false in the page headers. the visibility of a page is to determine if it should show up or not in the menu
