How to Auto Show Ship and Bill info on Order form with dual payment option

I have an order form and accept paypal and credit cards. However, when I create the order form the customer has to choose their payment option - credit card or paypal. How can I skip this step so that the billing and shipping option shows up automatically when they click on to the order form? Is there any code I can add somewhere? I’ve seen it before - here’s an example of what is happening:

And here’s an example of what I want to have happen:

As you can see in the first version the customer has to choose credit card or paypal.
In the latter version the fields show up automatically and at the bottom the customer can choose credit card or paypal

Anyone know how I can have the fields automatically show up like in the latter version? Any code I can use?
