Main menu\'s drop down menu

Hi Support

My client is using a MAC (browser Chrome) and apparently she isn’t able to see the whole length of the drop down menu bar.
She is reporting that the last navigation entry in drop down menu isn’t viewable.

How can this be fixed? Is this a setting element or change to the CSS-script?
If we need to make changes to the CSS-script, could I please ask you to provide me with the CSS-script?

As you can see there is a lot of space between each menu entry in the drop down menu, so maybe it is possible to reduce the height of each box.

Thank you in advance
&
Best regards
