[Gravity Forms] Creating product form

Hey Guys,

Gravity Forms seem to be away for the rest of the week so I thought I’d get a faster reply here.

I’d like to know how to create a form that is in 2-3 steps.

Eg. Upload image > Select Size > Purchase.

not exactly like that but the same concept.
I’d also like to create a drop down menu that has a few options, followed by an other sub menu depending on what was chosen on the last menu.

Eg. *People* *Pets* *Other*
If “People is selected the next option will ask “How many People”
Then they can select that. And all these values add up to a price that they will need to pay at the Purchase Step.

If you take a look here, They are also using Gravity Forms.

We’d basically like to to have the same function as that. except different Prices basically.

Thanks
