[Javascript] multi-Select under multi-Select

[Guillermo Payet]

Hello,

I'm building a form with 2 levels of multiple choice <select> field. There is a "subordinate" <select> whose contents depend on whatever is the "currently selected" option in the top select field.  

For an example of what I'm talking about, which works in Mozilla but not in Exploder, check out:

Finding out which option is the "currently selected" (even when others are selected too) is not a problem with Mozilla, since the <option> element does call a "onclick" handler.  The problem is with Explorer, which does not seem to call any handlers from the <option>s.  I could use an "onchange" handler on the <select> field, but "selectedIndex" just gives me the topmost selection of the selected group, instead of the one currently selected, as I would expect.

Any ideas?  I'm pretty lost on this one.
