Connecting Jquery Date-Pickers

I am using the formidable pro plugin and it contains the classis jquery date pickers.

Issue: I am trying to connect the date pickers because I want the second date to always follow the first. Like if you are booking the start and end dates on a hotel room, or outbound and an inbound airline ticket. Currently the two act completely independently of each of.

Question: Has anyone developed code that we could use to connect the two so that the second date can not be previous or equal to the first when submitted?

Thanks.
