I would like to create a form for customers to complete before purchasing specific items on a products page. The pop up would need to link up with the checkout when they finish selecting their products.
We will be having an event page were customers can build their own event. Though prior to them selecting the items they want to purchase, i want to have some information from them which will then be integrated to their check out automatically .
I have found an example of something similar on this page https://hireshop.valiant.com.au/interiors?choose=1
Once the customer has selected their delivery dates and location, this then stays with them until checkout and automatically fills the information where needed.
Is there a particular app that allows this or would this need to be coded into the website.
Thank you
