Drop-down-submenü

Hello,
I have entered the hint from this article https://www.ads-software.com/support/topic/drop-down-menu-152/#post-12560566 because the distance in the menu was too big for us. But unfortunately the further sub menus separate and are no longer active.

We are not able to reduce the distance of the sub menus, do you have a tip for us?

Greetings
