Tool tip to be list items?

Tool tip to be list items?

Hi,
 
Right now, the tool tip shows the "help" description you put in the field configuration.
But can the tool tip be configured to show each list item when it is hovered over?
In other words, I have a drop down list. But some of the items are longer than the field length which makes it harder to read them.  Can the tooltip be used to extend each list item's text?  I've seen this done before elsewhere, but can it be done in Creator?
 
I'd rather do this than expand the length of the field, which in turn, just creates the need for scollbars.
 
Thanks in advance.
