I want to implement the below use case in form which I saw in one our competition website. Consider an example, we are in product based company with Product A, B, C. On our website we have landing page for all these three product and on each page their is enquire now button which pop-up form.
Say if user is on product page A and clicks enquire now button then in the form product field is auto selected as A, same implies to other pages.
I realize I'm a little late to the party, but I've used Query Strings to achieve your intended goal. It saves you from having to create a lot of different forms, which is helpful if you have a lot of different products. Takes a bit of work to set it up, however:
