How to scroll horizontal in Palette

[newbie newbie]

Hi,
**

I have items in Palette that is wider than the box width. The tail-end of
items is clipped and not visible. Palette has automatic vertical scrolling
but not horizontal scrolling. How do I make horizontal scrolling possible?

Here is what I have tried at my css.

DIV.t-palette SELECT { overflow-x: auto !important; }  and

DIV.t-palette-available { overflow-x: auto !important; }  and

DIV.t-palette { overflow-x: auto !important; }



Any help would be much appreciated. Thanks.
