Examples Dropdown Menu Exceeds Screen Size

[torridgristle]

The examples menu up top, specifically the Filtering category, extends below my screen. Currently if I want to view everything I have to zoom the page out to uncover the content.

The drop menus need scroll bars, or to work in columns with a horizontal scrollbar for future proofing in case one of the menus somehow gets enough entries to fill the screen this way as well.
