I'm looking for a javascript drop-down for a date range that allows the user to select start and end dates from a single form field, similar to what exists in the Google Analytics UI.

Hello, I am currently working on building a very simple site for an open source research project for my University. I am using JQuery to animate the sub-navigation of the site.
