Different Date Pickers based on different option selected

Site URL: https://onyxhive.com.au

Hello,

I have a date picker in my additional forms when a product is added to the cart.

Since squarespace is so limited with shipping options, I need the date picker I already have to change to different set of requirements.

For example:

1. Customer adds cake to cart
2. Pop up appears as per normal
3. Customer selects "Victoria” state from the first drop down menu (I will have to add this)
4. The calendar changes to a whole new set of options and disables Saturday and Sunday delivery
5. If customer selects “new south wales”
6. The calendar changes back and enables Saturday and Sunday delivery

Any similar date pickers out there or how can I implement this?

Thanks
