Does anyone know of one?

I want a select menu that will submit upon selection rather than  
requiring a submit\_tag. Does anyone know of one?

You can do this rather easily (have a form submit based on a change to a  
form field) by using a javascript handler or if you prefer to keep  
within rails, you can use an observe\_field or observe\_form tag

Check into them, specifically observe\_field will automatically submit a  
form when a certain field is changed.
