is this possible?

I am using javascript to show and hide various sections of my site (using the mm_showhide script) i.e. on a particular mouseover or click different information is displayed. fairly standard i'm sure.

but I have the box that it is displayed in set at certain height, and want to be able to scroll the text within this box, if there is too much text.

any help suggestions appreciated

EDIT -- just noticed how similar this is to another thread below I think (about the showing/hiding tabs etc!)
