How to create a order form with 200 items?

Hello, 

I am looking for a widget that could

1. permit clients to order material without paying but still seing the amount of the total

2. permit at least 200 products to be listed

3. drop-downs to be hidden until one product is chosen then the next drop down appears to choose another tiem

4. products must have pricing attached to them and form can calculate total

5. client can choose number of products

6. I don't need payment instruction

it would be like a purchase order form but the one you have in widgets does not permit me to hide procucts...

thanks for the feddback 

Looking at your requirement, it seems that the purchase order payment form might be helpful. Since you say that you want to hide the products until one product is chosen, you may check the option to add the sub-products on the form.

If this doesn't work, unfortunately, there is no built-in function or widget available to achieve your requirement. However, you may set up the form using individual fields and hide the fields by using conditions.
