BB Menu: set delay on sub-menu disappearance


When hovering my menu items and going hover sub-menus if the mouse leave the list item (li) area the whole menu disappears immediatly. I would like to either have a delay after which the menu disappears if the mouse did not enter any menu item or the ability to widen the area around which the mouse is considered hovering the menu.

I looked online and on this forum but did not find any answer, I’m relatively new with BB so this might be my fault, any help or link to a solution would be greatly appreciated, thank you for reading.
