I have only just started using App Inventor and require a date picker.

I found one on the JQuery site but am not sure how to use JQuery.

Do I just download files and somehow link them to App Inventor on my PC?

Do I have to have JQuery on my phone to use the app or does the code get embedded into the app when I send it to the phone?

Sorry if these are basic questions but I can't find a 'start from the beginning' type guide on the site.

Many thanks
