Not OOB. You could fix it up with a little help from a CEWP.

I am all ears.

If you have a posting about this somewhere, please shoot me the link.

I don't have a post and unfortunately I don't have time right now. But
here is the idea.

Given that you have a collection of checkboxes, you write some
JavaScript to encapsulate them within a div that has a
style="overflow:auto".

OR, iterate the collection of checkboxes and convert them to options in
a select  list, or several columns of checkboxes, or whatever
presentation you want. Be careful to preserve the IDs of the checkboxes
for postback or create hidden input elements with the same IDs that
represent the selections that the user has made within your custom
presentation.
