635646 - Allow the scrollbar on <select size=n> (where n > 1) to be hidden via CSS

Status: NEW

(Core :: Layout: Form Controls, enhancement)

Description

Currently, the overflow property seems to do nothing on select elements that render as list boxes, and a scrollbar is always displayed. It'd be useful if authors could hide the scrollbar via CSS. I'm not sure if using "overflow" for this purpose would break the web, but if it does, this issue could be solved via an extension.

What's the use case of hiding part of the form control, exactly?  The point is to allow users to pick one of the options, no?

This is for the list box case (when size > 1 <select> displays as a list box), not the drop-down case. A scroll bar is always displayed on the list box, even when it's not necessary due to all items being visible.

That's a separate issue; we have existing bugs on not showing that.  Overloading the "overflow" property to work only in this case would be pretty weird.

Well, it would be nice to be able to unconditionally hide the scrollbar. In my case, I'd like to duplicate the functionality of the native scrollbar using custom code.
