Adding to select list

I have several select lists on a form generated via collection_select
pulling values from the database. What I would like to do is, if new
components need to be added to a select list (new options), I am
providing a link beside the select list which will pop-up a small form
to add a new item to the list. Upon saving the new item, I would like
the list on the form (parent window) to refresh, so that the new item
can be selected. I have tried both opener.location.reload(), which
updates the lists but unfortanately wipes out all fields on the form,
and window.opener.history.go(0), which keeps the field values, but does
not refresh the select lists as needed. Any suggestions on how I can
accomplish this? TIA.

How about refreshing the select list using rjs?
