Collapsible Table Column List Doesn't Scroll

Hi Guys,

I’ve got a table with a lot of columns - say 20 to 50, which are collapsible.

I’ve found an issue where if the user’s browser window doesn’t have the space to fit all the columns in the collapse list (when you click the little down arrow), the collapse list doesn’t scroll, making the columns at the bottom of the list unselectable.

Is there an ability to make this list scrollable / pagable / keyboard selectable, like a combo box so that longer lists can be navigated?
