Ajax link in select_tag options - problem


Hi all,

I am a newbie with RoR and am currently stuck with this problem:

I have an “ADD CATEGORY” option in the drop down menu for selection, ADD
CATEGORY is followed by categories I already added, now when I select
“ADD CATEGORY” option I need a DIV containing the form for adding the
category be displayed via AJAX.

Could anyone help me with this…
