I need a div that has a lot of content and scrolls horizontally. The content (inner divs) has dropdown menus, and when the menus are opened they are supposed to render beyond the outer div's borders. 
Like so:
But when i set
overflow-x: scroll;
overflow-y: visible;
my dropdowns aren't opened properly, they are contained within the wrapper div and I need to scroll down vertically to see them.

It looks like overflow-x:scroll overrides overflow-y:visible. What can I do about it?
