I can see it fine on mine (1980 wide) but I can see the above poster's issue.
Attached a screenshot with suggested solution.
Also - you can see where it overflows the right 'bound' of the main nadac site, and the above person's it overflows a lot more. You should be able to have your web developer contain it to the main page area (ie not overflow to the right) - if it 'would hit' that boundary, it shifts left rather than right (see sketch on my screenshot). It already flows left for data center's sub categories for me, so either it was a) programed to (and you could just also raw program the video run one to flow left instead of right) or b) the bounding area that determines flowing left or right is just off some in that it catches the data center's sub but not the video run one.
It probably has to do with people's exact settings. You can adjust in windows for example to zoom in tighter, especially on the high res screens people do that so things are not teeny tiny (I have mine set on the default 125%). Then within browser there are adjustments, I have mine set at 100% but many folk have it zoomed in there too. You won't allllways solve it for everyone, but if you have a bound so the dropdown menus match the main page bounds that should solve 99.99% I'd think...
