ajax and rails script for populating dropdown list values based on selected radio button on rails 3

does anyone knows what will be the possible ajax and rails script for populating dropdown list values based on selected radio button on rails 3 example there are two type of platform choices(windows, unix) of radio button then when you clicked the unix radio button, the dropdown listbox will filter only the unix type something(patch).

The idea is the dropdown has a contents already from the database (<%= f.select :other_platform, Patch.all.map {|p| ["#{p.patch_type} #{p.number}: #{p.summary}", p.id ] }, {:include_blank => true} %>) then I need to do is to "filter" only the values that has a windows type example base on the radio button that has been selected if you clicked the windows type then the dropdown menu will show only the windows type of patches and hide the unix type or the list that has a unix word on it like regx(checking the query)and if you choose or clicked the unix then only the unix type will appear at the dropdown menu

thanks please answer

This is very similar to cascading select boxes ... take a look at the code here - http://pullmonkey.com/2008/03/30/dynami … -on-rails/
