[Radiant] calendar_date_select

[roland]

Hi there

I am looking for a way to make the features of the rails plugin  
calendar_date_select in a mailer form.
http://github.com/timcharper/calendar_date_select/tree/master

Does soemthing like that allready exist in the Radiant environment?
Can I just simply drop in a rails plugin and do some plumbing (which  
steps?) and then use that plugin in the Pages?

Thanx Roland
